[zeroflag]

What changes were proposed in this pull request?

Stack advisor resulted an error because of incorrect indentation.

  File "/var/lib/ambari-server/resources/stacks/HDP/3.0/services/HIVE/service_advisor.py", line 196, in recommendHiveConfigurationsFromHDP30
    druid_coordinator_host_port = str(host['Hosts']['host_name']) + ":" + str(
UnboundLocalError: local variable 'host' referenced before assignment

I changed the 4 spaces wide indentation to 2 and extracted out the common logic.

How was this patch tested?

Triggered stack advisor by modifying hive config on a cluster that had druid and tez installed.
