----------------------------------------
> Fix memory leak in hive streaming
> ---------------------------------
>
> Key: HIVE-20979
> URL: https://issues.apache.org/jira/browse/HIVE-20979
> Project: Hive
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 3.1.1
> Reporter: Shubham Chaurasia
> Assignee: Shubham Chaurasia
> Priority: Critical
>
> {{1) HiveStreamingConnection.Builder#init() adds a shutdown hook handler via }}{{ShutdownHookManager.addShutdownHook but it is never removed which causes all the handlers to accumulate and hence a memory leak.}}
> {{2) AbstractRecordWriter creates an instance of }}FileSystem but does not close it which in turn causes a leak due to accumulation in FileSystem$Cache#map
