----------------------------------
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
