Lav Jain commented on AMBARI-15657:
-----------------------------------
Hi [~aantonenko], Thanks a lot for letting us know.
The rationale was that if some configuration change results in an ERROR, the
user should not be allowed to proceed. Otherwise, the validation should trigger
a WARN (instead of ERROR). Currently, there is no distinction between the two.
> HAWQ config should not allow multiple Master/Segment directories
