Description

The shell seems to hang longer than the normal client and then display uninformative messages when doing wrong things.

For example, inserting into a non-existing family or reading from a disabled table. I believe in both these cases, HTable will throw informative exceptions like InvalidFamilyException and TableDisabledException (need to confirm exactly what it does).

But in the shell, I get things like:

Inserting to a family that does not exist:

ERROR: org.apache.hadoop.hbase.client.RetriesExhaustedException: Still had 1 puts left after retrying 7 times.

Reading from a disabled table (this takes a long time before anything is displayed):

ERROR: org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact region server 10.0.0.4:62505 for region sample,,1286217181143.1459f8fdde55752fd91022fb1153d39a., row '', but failed after 7 attempts.
