Review request for Ambari, Alejandro Fernandez, Nate Cole, and Sumit Mohanty.
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
total 4
lrwxrwxrwx 1 root root 33 Dec 18 14:45 hcatalog -> /etc/hive-hcatalog/2.3.4.0-3485/0
drwxr-xr-x 2 root root 4096 Dec 18 14:45 init.d
lrwxrwxrwx 1 root root 32 Dec 18 14:45 webhcat -> /etc/hive-webhcat/2.3.4.0-3485/0
{code}
{code:title=This is bad - current for hcatalog is still 2.3.2, which has the symlink issue}
root@os-d7-dkezlu-ambari-hv-r-upg-7-re1-5:/usr/hdp/current/hive-webhcat/etc# ls -l /usr/hdp/current | grep hive
lrwxrwxrwx 1 root root 26 Dec 18 15:50 hive-client -> /usr/hdp/2.3.4.0-3485/hive
lrwxrwxrwx 1 root root 26 Dec 18 12:59 hive-metastore -> /usr/hdp/2.3.2.0-2826/hive
lrwxrwxrwx 1 root root 26 Dec 18 12:59 hive-server2 -> /usr/hdp/2.3.2.0-2826/hive
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.
