Hitesh Shah commented on TEZ-1758:
----------------------------------
Comments:
Mostly looks good.
Minor point related to:
{code}
- throw new SessionNotRunning("TezSession has already shutdown");
+ throw new SessionNotRunning("TezSession has already shutdown. "
+ + ((diagnostics != null) ? diagnostics : ""));
{code}
Would it make sense to have the message contain the yarn app state as well as
diagnostics?
Also, there is a minor inconsistency:
- in case for the above code, it uses "" when diagnostics is null
- In TezClientUtils, it says "Cluster diagnostics not found"
Is this because diagnostics is not set when state is FINISHED?
Also, the newly added unit test code has a lot of spurious whitespaces that
needs cleaning up.
> TezClient should provide YARN diagnostics when the AM crashes
