------------------------------

             Summary: ORC MemoryManager thread checks are fatal, should WARN 
                 Key: HIVE-13163
                 URL: https://issues.apache.org/jira/browse/HIVE-13163
             Project: Hive
          Issue Type: Bug
          Components: ORC
    Affects Versions: 2.0.0, 2.1.0
            Reporter: Gopal V
            Assignee: Gopal V


The MemoryManager is tied to a WriterOptions on create, which can occur in a different thread from the writer calls.

This is unexpected, but safe and needs a warning not a fatal.

{code}
  /**
   * Light weight thread-safety check for multi-threaded access patterns
   */
  private void checkOwner() {
    Preconditions.checkArgument(ownerLock.isHeldByCurrentThread(),
        "Owner thread expected %s, got %s",
        ownerLock.getOwner(),
        Thread.currentThread());
  }
{code}
