Siddharth Seth commented on TEZ-2776:
-------------------------------------
[~Sreenath] - if you plan on taking this up after TEZ-2670, please feel free to
assign the jira to yourself.
Another webservice which *may* be useful is to change the logging level for the
AM. I say maybe because by the time we figure out something is stuck, changing
the log level will likely not help much.
> Add a way to trigger a log dump from the AM at runtime
