Implementing Security Plugin

I am using apache ignite version 1.6 and trying to implement a security plugin by following the post (http://smartkey.co.uk/development/securing-an-apache-ignite-cluster/). Since the plugin API has changed after the blog post, I am unable to activate the plugin and configure only an authenticated a

ignition on yarn taking up all memory

I started ignite on yarn and then tried to submit a sample spark job. The ignition job took all available memory and so spark job was in "accepted" state forever. Spark job never had enough resources to run. So, I copied the following file to hdfs path /tmp/ignite and gave IGNITE_XML_CONFIG=/tmp/

Re: Embedded mode ignite on spark

Hi, For some reason you never have more than two server nodes in topology. So basically you Spark RDD is split between three Ignite RDD and you get incorrect results. Make sure that all nodes can connect to each other and that nothing is blocked by firewalls. Note that by default Ignite uses mult

Re: Cannot get cache through the REST API

Yuci, All the setting provided in documentation are based on testing of high-loaded applications. Small young size makes for on-heap caches where most of the objects are long living. However, there is no silver bullet and each use case can require its own tuning. -Val -- View this message in

Re: what are the differences between put and replace method

P.S. The replace() method is indeed equivalent to the snippet above, but it's an atomic operation. So it will atomically check the existence of the key and update the value. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/what-are-the-differences-between-pu

Re: IgniteException: No FileSystem for scheme: hdfs

Vikram, You should add JARs to the classpath, not directories that contain JARs. You can use wildcards as well, e.g.: /lib/hadoop/*.jar Please refer to Java documentation for more information on how to properly specify the classpath for you application. -Val -- View this message in conte

Re: Failed to wait for initial partition map exchange

Thanks for your suggestion, Vladislav. After use them, the same issue still happens. There must be some logic which causes the race contention between eviction and cache partition re-balance. Attached the logs for all the server nodes and all the config files. please help take a look, if any fur

Re: Rebalance is skipped

Hi, Sergii. I can't reproduce this issue. I have written test. https://github.com/EdShangGG/ignite/commit/8a9462c3a55c6c0317fb8bdc9ef26e12fdbcfb9a It uses the same configuration as you mentioned. Could you take a look? Maybe, I am missing something. On Tue, Aug 16, 2016 at 12:54 PM, Sergii Ty

Re: Fail to join topology and repeat join process

Thanks Vladislav. Will try to reproduce this issue again, and seems that this only happens in a big cluster. BTW, after the new node joins, and when it tries to do partition map exchange, seems that there's deadlock. In some nodes, "Failed to wait for partition map ..." and other nodes, "Failed t

Re: Failed to deserialize the job (.net) using code from examples

Thank you for your response and pointing to direction to think. I solved the problem: The issue was that nuget did not properly update the project. Just running update was not enough for some reason. 1. I've removed all Ignite nuget dependencies. 2. Just to be save manually cleaned debug/releas

Re: Who is going to take care of the off-heap memory?

Hello, You need take care, when dedicate minimum heap size, because JVM does not work with unsave memory directly. Copy data from off-heap to heap and deserialize occur over each cache operation (like get, getAll, execute query). Exception (Out of memory) will be thrown if heap was overflowed. Y
