> -----------------------------------------------------------------------------------------------
>
> Key: IGNITE-2146
> URL: https://issues.apache.org/jira/browse/IGNITE-2146
> Project: Ignite
> Issue Type: Bug
> Affects Versions: ignite-1.4, 1.5
> Environment: Mac OS X 10.11
> java version "1.8.0_66"
> Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
> Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
> Ignite 1.4.0 + Ignite-1.5.0-b1
> Reporter: Noam Liran
> Fix For: 1.5
>
> Attachments: stacktrace.txt

> We're deploying a service on a cluster group. The cluster group is filtered using a predicate. The predicate accesses a cache key to determine if it should return true for a node or not.
> If a new node joins the cluster while the predicate is running a deadlock is encountered: cache functions do not return and the node does not finish joining the cluster.
> I've created a sample program to reproduce this on 1.4.0 and also tried to reproduce it on 1.5.0-b1;
> On 1.4.0 the deadlock is usually reproduced, on 1.5.0-b1 it might take a few tries (I'm guessing it's a timing issue.. I tried to improve the odds of reproduction by using a countdown latch).
