Re: Ignite2.0 memory policy limit

Ajay, I managed to reproduce your issue. As I can see from logs you're starting Ignite using 32-bit JVM. To fix your issue just use 64-bit JVM or decrease initial/maxSize settings in memory configuration to something below 3 Gigs. Thanks, Sergey. On Wed, May 17, 2017 at 6:40 PM, Andrey

Re: Ignite2.0 memory policy limit

Hi Ajay, Ignite allocate memory by chunks. The first chunk is allocating on Ignite start and its size equal to initialSize. Other chunks allocated on demand and its size <=256M. Seems, your system can't allocate 4Gb memory as single chunk. What is /proc/sys/vm/overcommit_memory value? Try to set

Re: Igfs and MaprFs

Hi, Pranay, IGFS can run upon any file system that can be represented in terms of Hadoop file system API (namely as a org.apache.hadoop.fs.FileSystem). MapR file system also implements Hadoop file system API , namely, it has com.mapr.fs.MapRFileSystem . So, IGFS can successfully run upon.

Transaction management with Jboss and Ignite

Re: Allow ALL nodes to keep working when a new node joins the cluster

Hi Gordon. Client joining the cluster should not cause the server nodes slowdown. Did you observe such behavior? If that's the case, kindly take a thread dump for the node that is affected by slowdown. Kind regards, Alex. On Fri, May 12, 2017 at 8:36 AM, gordon.reid@ninemilefinancial [via

ConsulIpFinder (TcpDiscoveryIpFinder) issue

Hi, We are having trouble with our Ignite Cluster at start-up. If we attempt to start, say, 10 Nodes simultaneously, it appears that we get into a race condition and we get more than one Cluster created. We'd love to figure out a way around this. Our workaround today is to start 1 Node. Then

Hi, you can use "select count(*) from TableName" query. In order to limit query by particular local node you should set local flag to true and execute query on this node. In other words you should do something like this on your node: IgniteCache cache = ignite.getOrCreateCache(CacheName); //

Hi, You can provide IgnitePredicate instance to your CacheConfiguration. It will allow you create cache only on nodes that satisfy this predicate implementation. But cache itself will be available from all nodes that are want operate with data in this cache. On Tue, May 16, 2017 at 9:09 PM, Libo

Re: Understanding the mechanics of peer class loading

Hi Ilya, To my mind in this case it's not a problem of Peer Class Loading (PCL). Please note if you disable PCL in Ignite Configuration, test will fail anyway. In this test LocatorBiPredicate is taken by Jetty from the parent class loader (test launcher class loader) and cast to IgnitePredicate

Generally, you can't add new node while holding a lock. If you're holding locks for long period of time, I would recommend you to revisit the architecture. In any case, make sure that you properly release all the locks. Also I think you should to upgrade to the latest version, I believe there were
