Subject [jira] [Commented] (YARN-4444) TimelineClientImpl#doPosting should not fail on AbstractMethodError
Date Wed, 16 Dec 2015 00:34:46 GMT

Li Lu commented on YARN-4444:
-----------------------------

Thanks [~leftnoteasy]! I'm also thinking about the solution for now. Shall we make our best
effort to recover the timeline client on such kind of an error? The problem happened when
jackson tries to find a serializer to write json. If this is going to hide the problem then
probably the right thing to do is to crash the client anyways.

> We noticed there were application failures due to incompatible jackson changes. While
the compatibility story is on the ATS user's side, the timeline client should not fail the
whole process on AbstractMethodError.
