Tim Onyschak updated IGNITE-7090:
---------------------------------
Description:
If no acquirers are available to take permit of semaphore, the permit never
gets release and any further acquirerers will wait forever.
On node shut down DataStructuresProcessor.dsMap gets cleared out prior to event
listener being able to execute onNodeRemoved, hence owner is never cleared out
if it was unable to pass to a different acquirer.
