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

Hi Tim,

This patch did not change the original logic that SPARK was using. The incorrect logic was
reported in JIRA https://issues.apache.org/jira/browse/AMBARI-14557.

> Generate warning on deploy wizard UI when HAWQ segment is not co-located with a datanode.

> HAWQ can run on nodes that without hdfs deployed, that is access data remotely. However,
there are significant performance improvements if segments and datanodes are co-located.
