Re: How to exit from Client JVM while using Apache Ignite as Data Grid ?

Hi, Sounds like you didn't stop the node. Use ignite.close() or Ignition.stop() to achieve this. Let us know if it helps. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/How-to-exit-from-Client-JVM-while-using-Apache-Ignite-as-Data-Grid-tp3919p3954.html

Re: How to solve the 22 parameters' limit under scala 2.10 in the case class?

According to the trace you provided earlier, a different constructor was used to create the IgniteContext (the one that takes URL to XML file or the one that takes only SparkContext). Can you please double check you code? Probably you do this somewhere else? If you have a small example that

Re: How to end up the GC overhead problem in the IgniteRDD?

Hi, Your node has less than 1GB of heap memory (see the line below). Please allocate proper amount of heap to the server nodes, as Alexey suggested. ^-- Heap [used=528MB, free=42.03%, comm=911MB] In addition, if you're going to have more than 10 GB of data per node, I would recommend to use

Re: How to end up the GC overhead problem in the IgniteRDD?

Hi! Are you sure that your JVM is started with arguments like this: -Xms50g -Xmx50g ? By default ignite.sh starts node with 1Gb of heap. You may configure $JVM_OPTS variable with you JVM settings or start like this "ignite.sh -J-Xms50g -Xmx50g" On Wed, Apr 6, 2016 at 8:27 AM, F7753

Re: Why the client and server behaves like that?

Thanks a lot to let me know that. I think I'd use some time to refer to the ignite doc more carefully. And I created another topic about the GC OOM in my cluster: http://apache-ignite-users.70518.x6.nabble.com/How-to-end-up-the-GC-overhead-problem-in-the-IgniteRDD-tc3945.html -- View this

Is there some configuration I can use to monitor the GC behavior in the ignite? It is curious that a OOM happens on a node with more than 100GB RAM. -- View this message in context:

Hi agura, I refer to the source code of IgniteContext.scala, and notified that the ignite method will do "Ignition.start()" in a try-catch block. And the code I use is listed in this topic:

I run a spark streaming app in a ignite cluster overlap with a spark cluster(the server node of the ignite is also the worker node of the spark), the monitor page shows that only one task can success, then after a while an OOM error will be throwed

Re: Behavior of init() for clustered singleton

Following up on this... Sorry for the vague description of the problem, but we are experiencing objects "going null" (as if they were garbage collected?) in our clustered singleton. We have an instance variable of an object that is initialized in the service init() method. We have confirmed that

Re: Should Ignition.start() method to be called in a spark-igniteRDD app?

Hi, You should not call Ignition.start(). Ignite instance will be started during creation of IgniteContext. Could you please provide code snippet that creates IgniteContext or minimal reproducer example if possible? On Sat, Apr 2, 2016 at 8:42 AM, F7753 wrote: > What

Hi Prabuddha, Cache.get() operation returns copy of an object stored in a cache by default. If you set CacheConfiguration.setCopyOnRead to false then a copy won't be created but you mustn't modify returned object directly because it can effect consistency. In any case the objects returned by
