{code}
If an idle cluster, it shows nothing which makes sense I suppose. Then if
master is initializing, it dumps out master initializing exception ... which is
ok too.
> Expose processlist in shell (per regionserver and perhaps by cluster)

> HBASE-4057 adds processlist and it shows in the RS UI. This issue is about
> getting the processlist to show in the shell, like it does in mysql.
> Labelling it noob; this is a pretty substantial issue but it shouldn't be too
> hard -- it'd mostly be plumbing from RS into the shell.
