Gopal V updated HIVE-9976:
--------------------------
Description:
Race condition in the DynamicPartitionPruner between
DynamicPartitionPruner::processVertex() and DynamicPartitionpruner::addEvent()
for tasks which respond with both the result and success in a single heartbeat
sequence.
{code}

All 4 upstream vertices of Map 1 need to finish within ~200ms to trigger this,
which seems to be happening with LLAP.
