             Summary: GridDhtInvalidPartitionException in GridDhtPartitionDemander
                 Key: IGNITE-9803
                 URL: https://issues.apache.org/jira/browse/IGNITE-9803
             Project: Ignite
          Issue Type: Bug
          Components: cache
            Reporter: Semen Boikov
            Assignee: Semen Boikov
             Fix For: 2.8


Debugged failure of DynamicIndexPartitionedTransactionalConcurrentSelfTest.testConcurrentRebalance with GridDhtInvalidPartitionException, here is scenario where this error occurs:
 * test starts node1, node2, loads data
 * node3 is started, one partition is assigned to node2, node3 and node3 starts rebalancing
 * node4 is started, partition is re-assigned to node2 and node4
 * at this time rebalancing on node3 is in progress, is is going to handles supply message and at this moment exchange thread moves partition to RENTING state, at this moment it can not be moved to EVICTED since async partition cleanup is needed
 * at node3 thread doing rebalancing sees RENTING partition and gets GridDhtInvalidPartitionException

Probability of such failure is very high if insert sleep(5000) in the code doing async partition cleanup (PartitionEvictionTask.run).

 

I think fix for this issue is just handle GridDhtInvalidPartitionException in GridDhtPartitionDemander.
