-----------------------------------
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.
