Description: 
This JIRA handles multiple issues.

* If HBase Get does not fetch any rows for the query, we still try to parse the 
result and read fields. This leads to NPE while reading metrics. We should not 
attempt to read anything if no row is returned i.e. result is empty.
Found during web UI poc testing.
