             Summary: CLONE - [C++] Fix Handling do not retry exceptions
                 Key: HBASE-23490
                 URL: https://issues.apache.org/jira/browse/HBASE-23490
             Project: HBase
          Issue Type: Sub-task
            Reporter: guanyun
            Assignee: Enis Soztutar
             Fix For: HBASE-14850
         Attachments: hbase-18188_v1.patch, hbase-18188_v2.patch

Needed for HBASE-18061 and others. 

Java client relies on the exception hierarchy for DoNotRetryExceptions, which 
there is 40+ subtypes. The exceptions from the server side are rethrown in the 
client side (ConnectionUtils.translateException, etc) and the rest of the code 
deals with do-not-retry information by catching DoNotRetryIOException's (thus 
relying on exception hierarchy). 

This of course does not work on the C++ side, since we lack the info for the 
java class types. In case the exception happens in the RPC response, the server 
puts the do_not_retry information as a field in PB (see 
ExceptionResponse::do_not_retry PB message). However, in other settings, we 
just serialize the exception without do_not_retry information (see 
ResultOrException PB message). In some other settings, we can raise exceptions 
from the client-side (for example when table cannot be found in meta). 

We need a strategy to handle do-not-retry information uniformly, no matter they 
are coming from client side or server side.
