What version of Spark? I think locking of auto-login checkbox was fixed in 2.6.3. You can also delete spark.properties in C:\Documents and Settings\username\Application Data\Spark and then start Spark. It will lose all settings.
Aaron all spark client settings are kept in your users profile. In our environment this location is D:\profiles\username\ApplicationData\Spark I think 2.6.0 will keep it here if not check D:\profiles\username\Spark. You will want to open the spark.properties file. There is an entry autoLoginEnabled=true, you can either set this to false or just remove it. This will stop the Auto login.

The problem that I have, is that I can't find this property in my Spark Settings in Ambari UI! I need to set this (and some more) property via Ambari UI, to avoid a loss of these configurations after restarting the Spark component (a restart resets the config files according to the Ambari settings. And as I can't see this setting on Ambari UI I have no chance to set this persistent). How are these files and Ambari configs matched?
So, however the solution to change Spark's hive-site.xml file persistently (survive Spark service restarts) is to find them in Ambari Hive Configs and change them here. After restarting the Hive and afterwards the Spark component via Ambari, the Spark config file /usr/hdp/current/spark-client/conf/hive-site.xml is also updated from these values set in the Ambari Hive configs. Thank you @Doroszlai, Attila! See also the comment above:
@Daniel Mller this is a general comment so it might not help, but there's a set of custom property boxes under the Spark service Configs tab, including one called Custom spark-hive-site-override. The Spark guide describes a similar custom property step (for doAs support) on the following page in the Spark guide, under the Ambari subsection:
Glancing at your code: Is this your intended sendto address? IPAddress ip( 239, 255, 255, 250 ); That ought not to be an address on your LAN if it starts 239. Firewall problem: Can you ping that WAN address from another host, elsewhere on your LAN? Is the port blocked?
After 5 or so cycles, the code slows down to a crawl, with one request every 5 seconds or so, even with no delay. I wouldn't really care, but I still can't see any packets successfully transmitted and the standard response to the packet is not sent by the local devices. Anyone else have any ideas?
I thought I remembered reading that @AndyW got multicast to work sometime. I really need SSDP(and thus multicast), and am wondering if I need to get a better dev board, go bare metal with the CC3000, or just admit defeat.
The firmware does generate multicast packets every time it starts up, in a half-hearted attempt at playing nicely with other bonjour children, I suspect - so multicast is certainly possible. However, there are all kinds of subtleties like 224.x.x.x vs 239.x.x.x that can come into play with multicast. The devil is truly in the details.
Some folks appear to have had trouble UDP broadcast on 255.255.255.255 but had success on 168.0.1.255 type addresses. I don't know why this would be--the core software does not appear to look at IP addresses at all before passing them to the TI part.
The Spark software itself does a multicast UDP announcement to 224.0.1.187 on port 5683 and I know for sure that it works since I had some code looking for these "I'm awake!" messages at one time. I see @AndyW mentions these above as I am typing this!
Does anyone know what would cause the manual mode to not work? It connects to the WiFi the same, is it something to do with not enough spark.process(); calls? I would think since the UDP code is local, that would be the problem, unless automatic mode does more than I know about. Maybe some garbage collection or initialization routine.
Me too: UDP broadcasts and SYSTEM_MODE(MANUAL) - #2 by psb777 - Troubleshooting - Particle - but a very awkward workaround is that if you initially connect and then disconnect to the cloud then UDP broadcasts do work. It is reported that if you UDP broadcast to the network specific broadcast address e.g. 192.168.1.255 instead of 255.255.255.255 then this works without ever having a cloud connection - but I haven't tried that myself yet.
I was trying to run this thing on Makefile, so I changed the Makefile so that it runs /path/to/the/absolute/location/spark-submit instead of just spark-submit and now it just works. Who could have guessed.
The massive wildfires being fanned by hot and dry Santa Ana winds this week in parts of Southern California have written the latest tragic chapter in the story of the blazes that have incinerated vast swaths of the Golden State this year, destroying homes and businesses and displacing thousands of residents in the process.
But the power line problem has a positive side, according to Cliff Mass, a professor of atmospheric sciences at the University of Washington and a popular weather blogger. In regions vulnerable to wildfires across the nation, Mass contends that fierce winds will blow and dry weather will brown brush and overgrowth, but it takes a spark to start a fire. And the problem of surging power lines sent to the ground snaking and spitting sparks can be conquered by smart policy informed by advanced technology.
Mass said that weather and climate modeling has jumped in quality so much over the last five years due to increases in computing power and advances in imaging technology that weather and wind patterns can be seen clearly as they develop, providing plenty of time to take preventive action.
Mass said there is danger in writing off destructive wildfires as unavoidable acts of nature or lamentable symptoms of climate change. Governments and power providers can prevent the worst from happening by leveraging cutting-edge monitoring technology to guide power shutdowns and by doing the kind of tech updates that prevent short-circuited systems designed to combat blackouts from trying to turn themselves back on when power lines go down.
In a Los Angeles Times piece published last week, reporter Bettina Boxall outlined steps that one Southern California utility, San Diego Gas and Electric, has taken over the last decade to prevent its equipment from sparking in windy wildfire conditions.
In a ruling issued in 2012, four years after SDG&E applied to the California Public Utility Commission for the express authority to cut power to prevent wildfires, the commissioners wrote that the company had the authority but that, after a shut-off, it must justify the decision to cut power and demonstrate that it properly notified customers in advance, with an eye in particular to customers with disabilities and medical conditions.
Judges, lawmakers and regulators in California currently are considering updating a range of wildfire-related policies, including where to lay the financial responsibility for damage created by wildfires caused by sparking utility equipment and what kind of changes in land-use zoning, power-grid technologies and utility prevention strategies might have to be made to prevent future catastrophes.
As the Thomas Fire races across Ventura County, The New York Times reported that power failures in the area cut electricity to at least 186,000 residents and made it difficult for the firefighters working there to battle the flames, mainly by hampering communications among firefighting crews and with the public. Coordinating crucial air- and ground-team operations, for example, suffers when electricity fails, added Caley Fisher, spokesperson for the Colorado Division of Fire Prevention and Control, which is sending resources to help battle the Southern California blazes.
After that it is simply putting in a work order or a recraft order or do it yourself if you can and put in the spark of dreams (while removing any enchanced wyrm or aspect crest from Season 2) and do the craft.
Difficulty in adapting the works of Stephen King has long-plagued filmmakers. The prolific writer often creates characters with extensive backstory and the necessity to develop over the span of hundreds of pages, something a film confined to two hours can't always deliver without sacrificing the meat of the story or the spark of cinema. A prime example of this is "Firestarter," the latest reimagining of a King property. Starring an ill-cast Zac Efron and a wonderfully talented 12-year-old Ryan Kiera Armstrong, the adaptation takes on the science fiction-horror novel originally published in 1980 with tame sensibilities and a mild, though well-placed interest in the characters' emotional resonance. By default, there is simply not enough dynamic tinder - or realistic CGI - to set the film ablaze.
The 1984 "Firestarter," which propelled its 8-year-old star Drew Barrymore to peak child actor fame, had a similarly befuddling time translating the story effectively onto the screen. That film opened with its stars on the run, dodging highway traffic and comically rolling down hillsides to evade capture. This 21st-century retelling chooses instead to first establish our lead characters, allowing us to understand their gifts and organically "warm" up to the "on the lam" action that ensues. Unfortunately, at a lean 94-minute runtime, "Firestarter" doesn't have the time to do both well, and as charismatic as Efron is, this role as a father to a tween, while earnest, feels completely inauthentic. (Could this be the Millennial in me who has a hard time shaking the Disney teen heartthrob persona that Efron once embodied? Possibly.)
Efron's Andy McGee has a strong connection with his family and will stop at nothing to protect them, including using his gift that he calls "The Push." It's the ability to influence people's actions by looking them in the eye and telling them what he would like them to do. It's like mind control, but softer. He makes a small, off-the-books living by offering "life coaching" skills to help people quit smoking or gain confidence. He and his telekinetic wife Vicky (Sydney Lemmon) gained these powers, as well as mild telepathy, after they signed up to be lab rats for an experimental drug, developed and tested by a government agency known as the Shop.
