This is a Impala service-level health test that checks that enough of the Impala Llama ApplicationMasters in the cluster are healthy. The test returns "Concerning" health if the number of healthy Impala Llama ApplicationMasters falls below a warning threshold, expressed as a percentage of the total number of Impala Llama ApplicationMasters. The test returns "Bad" health if the number of healthy and "Concerning" Impala Llama ApplicationMasters falls below a critical threshold, expressed as a percentage of the total number of Impala Llama ApplicationMasters. For example, if this test is configured with a warning threshold of 95% and a critical threshold of 90% for a cluster of 100 Impala Llama ApplicationMasters, this test would return "Good" health if 95 or more Impala Llama ApplicationMasters have good health. This test would return "Concerning" health if at least 90 Impala Llama ApplicationMasters have either "Good" or "Concerning" health. If more than 10 Impala Llama ApplicationMasters have bad health, this test would return "Bad" health. A failure of this health test indicates unhealthy Impala Llama ApplicationMasters. Check the status of the individual Impala Llama ApplicationMasters for more information. This test can be configured using the Impala Impala service-wide monitoring setting.
