             Summary: HDP 2.1 install leaves deprecated params in mapred-site.xml, causes Hive failure
                 Key: AMBARI-5368
                 URL: https://issues.apache.org/jira/browse/AMBARI-5368
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 1.5.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 1.5.1


If Ambari 1.5.0 to install HDP 2.1, Hive fails. Tracing leads to a pair of deprecated params in mapred-site.xml. Removing the two params caused the Hive problem to go away. 

Mapred-site.xml having both new and deprecated properties. After deleting deprecated property hive works as expected.

| mapred.map.child.java.opts	| mapreduce.map.java.opts |
| mapred.reduce.child.java.opts 	| mapreduce.reduce.java.opts |


The problem is eliminated if I execute the following after installation:

sh /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin -port 8081 delete localhost c1 mapred-site mapred.map.child.java.optssh /var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin -port 8081 delete localhost c1 mapred-site mapred.reduce.child.java.opts
