Andrey Gura updated IGNITE-169:
-------------------------------
Description:
{{GridSessionCheckpointSelfTest.testSharedFsCheckpoint fails}} from time to
time.
The problem is that test-runner thread invokes {{ignite.compute()}} in async
mode and when all jobs are mapped it invokes {{processDelayedResponses}}
method. At this moment is possible that all responses are received but sys pool
threads don't invoke {{reduce}} method. test-runner thread polls delayed
responses from queue and invoke {{reduce}}. So test-runner thread "steals"
reduce job that is waitiong on latch that should be counted down by the same
thread.
Just run test N times in a loop in order to reproduce it.
