Shinichi Yamashita updated HDFS-5180:
-------------------------------------
Description:
In current trunk, it is output at DEBUG level for the processing time of all
RPC requests to log.
When we treat it by the troubleshooting of the large-scale cluster, it is hard
to handle the current implementation.
Therefore we should set the threshold and output only a slow RPC to node's log
to know the abnormal sign.
was:
Command and ugi are output now by audit log of NameNode. But it is not output
for the processing time of command to audit log.
For example, we must check which command is a problem when a trouble such as
the slow down occurred in NameNode.
It should add the processing time to audit log to know the abnormal sign.
