Subject [jira] [Comment Edited] (YARN-7434) Router getApps REST invocation fails with multiple RMs
Date Fri, 03 Nov 2017 01:26:00 GMT

---------------------------------------------------------------

Thanks [~elgoiri] for the patch, LGTM overall. Couple of minor comments:
* Can we move the local copy of members outside of *clone* as its invoked in loop?
* The patch itself looks quite straightforward but I am not sure how involved it is add multi-thread,
i.e. multi - RM tests?

> Router uses threads to invoke getApps in parallel with multiple RMs and has a concurrency
bug caused by sharing of the HTTP request object. This jira tracks the changes to fix the
multi-threading issue by cloning the request.
