[#2]

and normal ambari hive it working? weird error, like hadoop is not running.

Is HDFS in read only mode? Drive issues? Everything else working? Any other logs.

Is hdfs in standby? Usually I encounter this when HA is enabled and you're hitting same node. I would check name service ID as both maybe referencing same node. It is easy to fat finger this. alzo make sure proxy user is set http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.2.0/bk_ambari-views/content/settings_and_cluster...

If all else fails use REST API to diagnose https://community.hortonworks.com/articles/72110/ambari-views-rest-api-overview.html
