Attachment: HDFS-13411.001.patch

> Key: HDFS-13411

> Project: Hadoop HDFS
> Issue Type: Improvement

> Today when one RPC to namenode locks FSNameSystem for a long time, it would
> print the stacktrace to the namenode log. However all we know from this log
> is the operation name to the Namenode(such as create, delete).
> It should print more information about the rpc call(like caller name, caller
> ip, operation src), which blocks the namenode. So we can have a better tuning
> to the HDFS.
