Siddharth Seth commented on TEZ-2176:
-------------------------------------
[~vasanthkumar] - thanks for pointing out the limitation on markers. Missed
that bit. I think we're fine moving these messages to ERROR in that case,
instead of depending on log4j directly.
Regarding the version change, lets not do that in this jira. There may be
additional bits to look at where we actually change log files using log4j APIs
directly.
[~hitesh] - the 2.x change will be a separate jira. Will need some testing to
see what happens if log4j2 and log4j1.x are on the classpath. Also the
slf4j-lo4j12 / slf4j-log4j2 bindings. We can control the version shipped by Tez
- but these may come in externally, in which case some testing will be required.
> Move all logging to slf4j
