-------------------------------------
I am also quite late on this, but [~cnauroth] if you still have bandwidth to
review the changes, can I prepare a PR in the next weeks?
> Set NameNode RPC server handler thread name with more descriptive information
> about the RPC call.

> Key: HDFS-11063
> URL: https://issues.apache.org/jira/browse/HDFS-11063
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: Chris Nauroth
> Priority: Major
>
> We often run {{jstack}} on a NameNode process as a troubleshooting step if it
> is suffering high load or appears to be hanging. By reading the stack trace,
> we can identify if a caller is blocked inside an expensive operation. This
> would be even more helpful if we updated the RPC server handler thread name
> with more descriptive information about the RPC call. This could include the
> calling user, the called RPC method, and the most significant argument to
> that method (most likely the path).
