Description

In general, the script alerts need logging to cover error scenarios.

For example:
ambari-server/src/main/resources/common-services/HIVE/0.12.0.2.0/package/alerts/alert_webhcat_server.py

      json_response = json.loads(stdout)
    except Exception, exception:
      return (RESULT_CODE_CRITICAL, [str(exception) + str(stdout)])

If the response is not a valid JSON Ambari should log the content rather than just reporting that json could not be parsed through the alert text.

Similar enhancements may be needed in several script based alerts. At least, lets cover all the three alert scripts that are in HIVE.
