Contributor guide
Research direction
The issue names the query-timeout-thread and reports many waiting threads in Kyuubi 1.9.1, but provides no source file, test, logs, or configuration details. Start by locating the query-timeout-thread implementation and reproduce or inspect thread creation; done means identifying the cause and demonstrating that waiting threads no longer accumulate, with a regression test or documented evidence.
