Github user steveloughran commented on the issue: https://github.com/apache/spark/pull/22186 The latest patch builds locally Maven test outcome * lots of json missing method errors, clearly jackson version problems of some kind * I don't see log messages of hive shutdown appearing in the output, though after all the tests finish I do get a log showing the FS cleanup is going on ``` 18/08/28 22:09:58 INFO ShutdownHookManager: Shutdown hook called 18/08/28 22:09:58 INFO ShutdownHookManager: Deleting directory ...spark/sql/hive-thriftserver/target/tmp/ ``` I think it might be possible to actually test whether the shutdown hook was added by calling remove(hook) in a test and verifying that the hook was found, that is : it was registered. Some caching of the hook and a package-level removeHook method in the HiveServer, though wiring it all the way up to a test case would be tricky...
