Suresh Srinivas commented on HADOOP-7272:
-----------------------------------------
I committed the change to 0.20.security branch. I am not going to commit this
to 0.20.205 branch, as this is not a big issue. LOG.info is surrounded by
LOG.isDebugEnabled(). Hence for setup where debug is not enabled, this log is
not printed. If debug is enabled, it just gets printed as info instead of debug.
> Remove unnecessary security related info logs

> Two info logs are printed when connection to RPC server is established, is
> not necessary. On a production cluster, these log lines made up of close to
> 50% of lines in the namenode log. I propose changing them into debug logs.
