Eric Yang commented on YARN-7381:
---------------------------------
I verified that UGI.doAs call to ApplicationManager, the rpc channel throws
empty exception with this option turned on. It looks like rpc protocol buffer
is not crafted to serialize the extra information triggered by debug_info. It
is definitely not safe to leave the debug-info enabled with current Hadoop rpc.
I recommend to revert this patch until rpc layer can handle debug information
gracefully.
> Enable the configuration: yarn.nodemanager.log-container-debug-info.enabled
> by default in yarn-default.xml
