-------------------------------------
Summary: [C++] Fix Handling do not retry exceptions
Key: HBASE-18188
URL: https://issues.apache.org/jira/browse/HBASE-18188
Project: HBase
Issue Type: Sub-task
Reporter: Enis Soztutar
Assignee: Enis Soztutar
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.
