> "add resource <remote-uri>" command downloads the resource file to location specified
by conf "hive.downloaded.resources.dir" in local file system. But when the command above is
executed concurrently to hive-server for same file, some client fails by VM crash, which is
caused by overwritten file by other requests.
> So there should be a configuration to provide per request location for add resource command,
something like "set hiveconf:hive.downloaded.resources.dir=temporary"
