---------------------------------------
Pushed this to 1.2 and 1.1 as well, since we have the HBASE-16604 there.

> broke co-processors (such as Phoenix) throwing DoNotRetryIOExceptions when
> scanning a table. This change rethrows them as UnknownScannerExceptions which
> the HBase client will retry on. This is unintended behavior since
> co-processors should be able to throw DoNotRetryIOExceptions back to the
> client. This came up through a phoenix IT when trying to upgrade to HBase
> 1.3.0 https://github.com/apache/phoenix/pull/230
