> {{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
