Jonathan Hurley updated AMBARI-14437:
-------------------------------------
Description:
Errors are encountered while restart Hive HCat client when it is not located on
a host which also has WebHCat daemon.

The problem is that {{hcat_client.py}} must write out configs to
{{/usr/hdp/current/hive-webhcat/etc/hcatalog}} but {{hcat_client.py}} doesn't
{{hdp-select}} anything.
So that the "current" pointers are never changed. {{hcat_client.py}} should
probably {{hdp-select hive-webhcat}} since there is no {{hcat-client}} in
{{hdp-select}}.
