      Description

      This was reported by a customer. Customer accidentally added a config of type
      `hivesite` to a config group.

      *Call*

      curl 'http://ambhost:8080/api/v1/clusters/TSGHDP/config_groups/3' -X PUT -H "X-Requested-By: ambari" --user admin:admin --data '[{"ConfigGroup":{"id":3,"cluster_name":"HDP","group_name":"Hive_custom_group","tag":"HIVE","description":"","hosts":[

      {"host_name":"abc.local"}

      ],"service_config_version_note":"hive custom group tx timeout
      property change","desired_configs":[{"type":"hivesite","tag":"newversionforjdbcurl","properties":{"hive.txn.timeout":"310","javax.jdo.option.ConnectionURL":"jdbc:mysql://abc.local/hive2?createDatabaseIfNotExist=true"}}]}}]' --compressed

      This resulted in ambari-server failing to process agent heartbeat and throwing
      NPE.
