Configuration of HiveServer2MetaConnTest

This test monitors the usage of the connection pools on the Metastore of the target Apache Hive data warehouse. Besides, this test accurately pinpoints the connection pool that is being over-utilized and hence running out of free connections. In the process, this test also reports the average time taken for a connection to be granted from each connection pool. Using this test, administrators can easily figure out the connection pool that is busy.

This page depicts the default parameters that need to be configured for the HiveServer2MetaConnTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the IP address of the host for which this test is to be configured.

• In the PORT text box, specify port number through which the Apache Hive communicates. The default port is 10002.

• By default, the SSL flag is set to False, indicating that the target Apache Hive is not SSL-enabled by default. To enable the test to connect to an SSL-enabled Apache Hive, set the SSL flag to True.

• The DD Frequency refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time the test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
