Lars Hofhansl commented on HBASE-6474:
--------------------------------------
There are beginnings of this in the form of subclasses of IOException. For
example unrecoverable actions throws back a subclass of DoNotRetryException to
a client.
> Separate exception types for recoverable and non-recoverable errors
