[jira] [Created] (HIVE-10693) LLAP: DAG got stuck after reducer
fetch failed
Sergey Shelukhin created HIVE-10693:
---------------------------------------
Summary: LLAP: DAG got stuck after reducer fetch failed
Key: HIVE-10693
URL: https://issues.apache.org/jira/browse/HIVE-10693
Project: Hive
Issue Type: Sub-task
Reporter: Sergey Shelukhin
Assignee: Siddharth Seth
Internal app ID application_1429683757595_0912, LLAP application_1429683757595_0911. If someone without access wants to investigate I'll get the logs.
I've ran into this only once. Feel free to close as not repro, I'll reopen if I see again :) I want to make sure some debug info is preserved just in case.
Running Q1 - Map 1 w/1000 tasks (in this particular case), followed by Reducer 2 and Reducer 3, 1 task each, IIRC 3 is uber.
Fetch failed with I'd assume some random disturbance in the force:
