>         Environment: spark on hive long running service

> On the long-running server of spark on hive, if a large number of tables are created, OOM will occur because the IsolatedClientLoader object cannot be released.
> The Hive Client should adopt the singleton mode, which can avoid the oom caused by the unreleased IsolatedClientLoader object.
