Dmytro Grinenko commented on AMBARI-25591:
------------------------------------------
not a lot information available, basically nothing to tell without full stack
trace.
As for the recommendation, verify configured user and password in the
ambari.properties; The warning log might be a result of previous error.
> org.postgresql.util.PSQLException: FATAL: password authentication failed for

> Ambari server is continuously logging password authentication failed for user
