Subject [jira] [Created] (IGNITE-7010) Ignite hangs on cache destroy called from IgniteBiPredicate - Ignite Events

---------------------------------------------

             Summary: Ignite hangs on cache destroy called from IgniteBiPredicate - Ignite
Events
                 Key: IGNITE-7010
                 URL: https://issues.apache.org/jira/browse/IGNITE-7010
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.3
            Reporter: Krzysztof Chmielewski


Ignite hangs trying to delete cache as a response to Ignite Event EventType.EVT_NODE_LEFT.
Code to reproduce this issue is available at https://github.com/kristoffSC/IgniteHang

Reproduce instructions:
# Put break points in ServerStarter.java line 40 and 42.
## Start ServerStarter as Java Application in Debug mode.
### Start ClientStarter as Java Application. After ClientStarter ends, ServerStarter detects
EventType.EVT_NODE_LEFT and will stops at line 40 (BP). Try skip to next line (ignite.destroyCache("testCache");)
and then try skip one more line. Ignite will hang at line 41.

This "hang" prevents other nodes from connecting to this running/hanging Ignite Server.

Thread that stuck is "disco-event-worker". It waits on {code} return stopFut.get() {code}
in IgniteKernel.class at line 3146
