HiveServer2 Health Tests

This HiveServer2 health test checks that the number of file descriptors used does not rise above some percentage of the HiveServer2 file descriptor limit. A failure of this health test may indicate a bug in either Hadoop or Cloudera Manager. Contact Cloudera support. This test can be configured using the File Descriptor Monitoring Thresholds HiveServer2 monitoring setting.

Short Name: File Descriptors

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. See that host's status page for more details.This test can be enabled or disabled using the HiveServer2 Host Health Test HiveServer2 monitoring setting.

This HiveServer2 health test checks that the filesystem containing the log directory of this HiveServer2 has sufficient free space. This test can be configured using the Log Directory Free Space Monitoring Absolute Thresholds and Log Directory Free Space Monitoring Percentage Thresholds HiveServer2 monitoring settings.

Short Name: Log Directory Free Space

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.

Short Name: Process Status

This HiveServer2 health test checks that the HiveServer2 has not recently exited unexpectedly. The test returns "Bad" health if the number of unexpected exits goes above a critical threshold. For example, if this test is configured with a critical threshold of 1, this test would return "Good" health if there have been no unexpected exits recently. If there has been 1 or more unexpected exits recently, this test would return "Bad" health. This test can be configured using the Unexpected Exits Thresholds and Unexpected Exits Monitoring Period HiveServer2 monitoring settings.
