> 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.
