Configuration of HiveServer2ExeEngTest

This test reports the number of tasks executed by the engines namely Mapreduce, Spark and Tez in the target Apache Hive and helps the administrators to sort out which engine is imposing the maximum load on the Apache Hive data warehouse.

This page depicts the default parameters that need to be configured for the HiveServer2ExeEngTest 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.
