Description

There is a carriage return in the document before zookeeperNamespace in the hiveserver2 ha docs.

<provider>
<role>ha</role>
<name>HaProvider</name>
<enabled>true</enabled>
<param>
<name>HIVE</name>
<value>maxFailoverAttempts=3;failoverSleep=1000;enabled=true;zookeeperEnsemble=machine1:2181,machine2:2181,machine3:2181;
zookeeperNamespace=hiveserver2</value>
</param>
</provider>

with this carriage return zookeeperNamespace becomes null in knox causing the stacktrace.

Caused by: java.lang.NullPointerException

Please correct the documentation so that the zookeeper line is all together without the carriage return.
