Bugs: AMBARI-14437
https://issues.apache.org/jira/browse/AMBARI-14437
Repository: ambari
Description
-------
Errors are encountered while restart Hive HCat client when it is not located on
a host which also has WebHCat daemon.
{code:title=This is good - the pointers have moved for 2.3.4}
root@os-d7-dkezlu-ambari-hv-r-upg-7-re1-5:/usr/hdp/current/hive-webhcat/etc# ls
-l /usr/hdp/2.3.4.0-3485/hive-hcatalog/etc

{code:title=This is bad - current for hcatalog is still 2.3.2, which has the
symlink issue}

lrwxrwxrwx 1 root root 35 Dec 18 12:59 hive-webhcat ->
/usr/hdp/2.3.2.0-2826/hive-hcatalog
{code}
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}}.

OK
Upgraded cluster with multiple hcat clients not located with other hive
components.
