             Summary: Ambari Alert - HiveServer2 Process - False negative in Certain Scenarios
                 Key: AMBARI-24582
                 URL: https://issues.apache.org/jira/browse/AMBARI-24582
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
             Fix For: 2.7.2


The Hive Alert & Hive Service Check both share the same logic from {{hive_check}} which attempts to execute something similar to:

{code}
beeline -u '%s' %s -e ';' 2>&1| awk '{print}' | grep -i -e 'Connection refused' -e 'Invalid URL'"
{code}

This type of negative condition checking misses a lot of failures, such as permission problems and SSL/JKS problems. Instead, we should change this to a positive check.

- Add the {{-n}} option to specify the hive user since the hive warehouse inode is protected. This option is ignored for Kerberos
- Change the grep to look for positive conditions
