[jira] [Updated] (HIVE-15296) AM may lose task failures and not reschedule when scheduling to LLAP

2016-11-30 Thread Sergey Shelukhin (JIRA)

Sergey Shelukhin updated HIVE-15296:

Attachment: HIVE-15296.patch

Not 100% sure of the root cause.
1) The difference in heartbeat mechanisms before and after the task is running 
is actually irrelevant, since it is only present on LLAP side.
2) The tracking and killing itself is done by Tez AM. Unless there's a bug in 
Tez, which I cannot see in the code, it should work.

The problem must be in the part that connects these together. Upon examination, 
I wonder if having heartbeats from the node (host+port) blindly heartbeat all 
the tasks that AM *thinks* are on the node is the culrpit? The restarted LLAP 
can heartbeat in time. 
This patch propagates unique daemonId usage to node heartbeats (and submit task 
response, to know the original unique node ID for the task in the first place).
I left some TODO comments to improve the handling for this, but for now I'd 
rather not rewrite EntityTracker entirely to use unique ID everywhere.

[~sseth] [~prasanth_j] can you take a look?
