 LLAP: Possible race condition in DynamicPartitionPruner for 200ms tasks
 

 Key: HIVE-9976
 URL: https://issues.apache.org/jira/browse/HIVE-9976
 Project: Hive
  Issue Type: Sub-task
  Components: Tez
Affects Versions: llap
Reporter: Gopal V
Assignee: Gunther Hagleitner
 Attachments: llap_vertex_200ms.png


 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 consistently happening with LLAP.

I'll take a look. Assuming this was run with Tez 0.7 snapshot ?
