[jira] [Created] (IGNITE-9436) Compute task may cause a deadlock on node stop.

Andrew Mashenkov created IGNITE-9436:
----------------------------------------

             Summary: Compute task may cause a deadlock on node stop.
                 Key: IGNITE-9436
                 URL: https://issues.apache.org/jira/browse/IGNITE-9436
             Project: Ignite
          Issue Type: Bug
          Components: compute
            Reporter: Andrew Mashenkov


Task that is waiting for async compute call result on reduce may lead to deadlock on node stop.

This task will hold GridTaskProcessor.readlock and waits for remote call result on future.
At that time node stopping thread will try to acquire GridTaskProcessor.writeLock.
GridTaskProcessor job message listener will try to acquire GridTaskProcessor.readLock with no success.

So, grid can't be stopped as there is a task on fly, but remote call result also can't be delivered to task.
