ASF GitHub Bot commented on TWILL-61:
-------------------------------------
Github user chtyim commented on the issue:
https://github.com/apache/twill/pull/67
I've addressed the comments and fixed one more issue (one deletion failure,
if the node not exist, we can just go ahead and recreate the node instead of
failing).
Also refactored the callback code a bit to try to make it cleaner.
> Second launch attempt of AM always failed

> YARN would make multiple attempts to launch an application. Currently second
> or above attempts would always fail due to creation of /runId/state node in
> ZK fail (node exists) because runId is generated on client side and doesn't
> change between attempts.
