> 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.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
