Description

Install Ambari-1.6.1 and deploy HIVE/WEBHCAT services. Upgrade to Ambari-2.1.0
and you will notice that:

• WEBHCAT_SERVER does not appear as a component on the HIVE dashboard
• There are no host components listed under HIVE/components/WEBHCAT

The reason is that while latest Ambari deleted WEBHCAT as a service, during
upgrade, the folders from the prior installation remain. This confuses the API
layer.

For example, this is the fix that was recommended to a customer.
To fix, remove the WEBHCAT service definition folders from `/var/lib/ambari-
server/resources/stacks/HDP` on the ambari-server host.

cd /var/lib/ambari-server/resources/stacks/HDP
find . -name WEBHCAT
./2.1/services/WEBHCAT
./2.1.GlusterFS/services/WEBHCAT
./2.0.6/services/WEBHCAT
./2.0/services/WEBHCAT
./2.0.6.GlusterFS/services/WEBHCAT
[root@smam161-1 HDP]# mv ./2.1/services/WEBHCAT /tmp/WEBHCAT-2.1
[root@smam161-1 HDP]# mv ./2.0/services/WEBHCAT /tmp/WEBHCAT-2.0
[root@smam161-1 HDP]# mv ./2.0.6/services/WEBHCAT /tmp/WEBHCAT-2.0.6
ambari-server restart
