             Summary: Precondition checks should not fail the merge task in 
case of automatic trigger
                 Key: HIVE-7548
                 URL: https://issues.apache.org/jira/browse/HIVE-7548
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: 0.14.0
            Reporter: Prasanth J
            Assignee: Prasanth J


ORC fast merge (HIVE-7509) will fail the merge task in case if any of the 
precondition checks fail. Precondition check fail is good for "ALTER TABLE .. 
CONCATENATE" but not for automatic trigger of merge task from conditional 
resolver. In case if a partition has non-compatible ORC files for merging then 
the merge task should ignore it and not fail the task.
