Description

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.

(ref: http://hadoop.apache.org/docs/r2.3.0/hadoop-project-dist/hadoop-common/DeprecatedProperties.html)

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
