HAWQ service check Fails From Ambari

HAWQ service check Fails From Ambari

Explorer

We have small Hadoop-Hawq Cluster. In that, once of slave host service fails When I am executing the check of HAWQ services using Ambari UI..

Getting following error From Ambari UI:

  **stderr:** 
  Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/stacks/PHD/3.0/services/HAWQ/package/scripts/service_check.py", line 9, in <module>

  Exception: gpstate command returned non-zero result: 255. Out:  Error: Permission denied, please try again.
  Permission denied, please try again.
  Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
  **stdout:**
  (255, '', 'Permission denied, please try again.\r\nPermission denied, please try again.\r\nPermission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n')

Any help on it would be much appreciated ?

Hi @vij singh

I think root user is not authorized for passwordless login to the HAWQ master . Could you please make sure you have password less access for root and gpadmin user in the cluster .
