Measures reported by HiveServer2AllQyTest
The efficiency of the Apache Hive service can be measured by the quality of the queries. By periodically checking the feedback returned by the data query engine, administrators can determine the number of queries that may have to be optimized before being executed. The Hive Query Statistics test helps administrators perform this check at regular intervals. With the help of the metrics reported by this test, administrators can quickly figure out the number of queries that succeeded and the queries that failed.
Outputs of the test: One set of results for the target Apache Hive
