Review request for Ambari, Sumit Mohanty and Sid Wagle.
Bugs: AMBARI-7739
https://issues.apache.org/jira/browse/AMBARI-7739
Repository: ambari
Description
-------
Patch on top of change already committed.
Create an Ambari 1.7.0 cluster with HDP 2.2.1, and install HDFS, Tez, MR, Hive,
Zookeeper.
After switching the hive.execution.engine from "mr" to "tez", attempting to run
the hive shell generates an error.
Logging initialized using configuration in
file:/etc/hive/conf.server/hive-log4j.properties

In the original patch, https://reviews.apache.org/r/26591/ , the hadoop-env is
stored as xml and needed to escpae && as && but it ends up appearing in
that same way in the hadoop-env.sh file, which prevents it from working.
So intead of using &&, use nested ifs.

Testing
-------
Deployed a new cluster with the changes to hadoop-env.xml and verified that
hive on tez was able to start.
I did need to run the following first,
hadoop fs -mkdir /apps/tez
hadoop fs -copyFromLocal
/usr/hdp/current/tez-client/lib/tez-0.6.0.2.2.0.0-913.tar.gz
/apps/tez/tez.tar.gz
hadoop fs -ls /apps/tez/
Thanks,
Alejandro Fernandez
