Hi, The correct way to pass the multiple configurations is that it should be passed along with the --conf. Ex: spark-submit --conf org.spark.metadata =false --conf spark.driver.memory=10gb Thanks AK

Strangely when I tried to modify the tez.am.resource.memory.mb under Tez yesterday it wasn't taking effect. However, it does seem to be taking effect now. Appreciate your inputs.

@spolavarapu thank! It is exactly my case

@Vishal Prakash Shah The Hive Metastore database in PgSQL uses upper case object names. In PostgreSQL to access these upper case objects you have to quote those objects. So in the example you provided you will have to change the query to look something like below: SELECT * FROM "TBLS"; HTH

That worked like a charm Vineet. Appreciate that tip. It worked for me as well.

This turns out to be an issue with something else in HAWQ 2.0.0. Since libhdfs3 and libyarn uses the same kerberos keyfile. The application was failing in the event there wasn't any activity through libyarn for long time which in turn meant that login() function wasn't called. The problem is documented in https://issues.apache.org/jira/browse/HAWQ-940 The issue is identified and addressed. Moreover, there wasn't anything in resource manager logs except for the container release logs.

I would recommend you to change the "desired_state" in the table "servicecomponentdesiredstate" under ambari database. You can update the values where service_name = 'RANGER_KMS'.
