> When HAWQ is in the cluster with YARN HA and Kerberos enabled, the segments are down as they cannot connect to YARN RM.
> The following updates are required:
> 1. add hadoop.security.authentication = kerberos in yarn-client.xml
> 2. add 2 properties to core-site.xml:
> <property>
>    <name>hadoop.proxyuser.postgres.hosts</name>
>    <value>*</value>
> </property>
> <property>
>    <name>hadoop.proxyuser.postgres.groups</name>
>    <value>hadoop</value>
> </property>
> 3. on every node:
> sudo useradd postgres
> sudo usermod -a -G hadoop postgres
