Description

Before HBASE-9899 is implemented, and after HBASE-3787, HBase throws OperationConflictException when client retries an already-successful non-idempotent request because the response didn't reach the client.
Integration tests run into this when CM kills servers hard during relatively-recently-added appends and increments. They need to handle this, read verification would make sure the results are still correct
