Zhijie Shen commented on YARN-2262:
-----------------------------------
[~nishan] and [~Naganarasimha], I've a general suggestion on this issue.
According to the logs, the problem is likely to be related to the FS history
store. On the other side, we're seeking rebasing on the timeline store to
persist the generic history data (See YARN-2033 for the motivation and the more
details). Given this is done, we may deprecate the current FS history store
because there are limitations around the FS history store, and it is expensive
to maintain two store interfaces.
It's always welcome if you'd like to help fix the bug, but I hope you're aware
of this plan, in case your effort is likely not to be leveraged. If you have
bandwidth, I would appreciate if you can help with other issue such as
YARN-2033, where I've a patch available for the timeline store based generic
history service, but I still didn't have a chance to test it with RM restart.
Anyway, thanks for your interest on the timeline server. Please feel free to
share your thoughts.
