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.
