HiveServer2 Host Health
This HiveServer2 health test factors in the health of the host upon which the HiveServer2 is running. A failure of this test means that the host running the HiveServer2 is experiencing some problem.

HiveServer2 Process Status
This HiveServer2 health test checks that the Cloudera Manager Agent on the HiveServer2 host is heart beating correctly and that the process associated with the HiveServer2 role is in the state expected by Cloudera Manager. A failure of this health test may indicate a problem with the HiveServer2 process, a lack of connectivity to the Cloudera Manager Agent on the HiveServer2 host, or a problem with the Cloudera Manager Agent. This test can fail either because the HiveServer2 has crashed or because the HiveServer2 will not start or stop in a timely fashion. Check the HiveServer2 logs for more details. If the test fails because of problems communicating with the Cloudera Manager Agent on the HiveServer2 host, check the status of the Cloudera Manager Agent by running /etc/init.d/cloudera-scm-agent status on the HiveServer2 host, or look in the Cloudera Manager Agent logs on the HiveServer2 host for more details. This test can be enabled or disabled using the HiveServer2 Process Health Test HiveServer2 monitoring setting.
