> There is a weird interaction between the shell and HBA. When you try to close
> a region that doesn't exist, it doesn't throw any error:
> {noformat}
> hbase(main):029:0> close_region 'thisisaninvalidregion'
> 0 row(s) in 0.0580 seconds
> {noformat}
> Normally one should get UnknownRegionException. Starting the shell with "-d"
> I see what a non-shell user would see along with a ton of logging from ZK
> (skipped here):
> {noformat}
> INFO client.HBaseAdmin: No server in .META. for thisisaninvalidregion;
> pair=null
> {noformat}
> But again this is not the right message, it should have shown
> {noformat}
> INFO client.HBaseAdmin: No server in .META. for thisisaninvalidregion;
> pair=null
> {noformat}
> And this is because that part of the code treats both UnknownRegionException
> and NoServerForRegionException like if it was the same thing.
> There is also some ugliness in flush, compact, and split but it normally
> doesn't show since the code treats everything like it's a table and sends a
> TableNotFoundException.
> This jira is about making sure that the exceptions are correctly coming out.
