----------------------------------------
Summary: 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
{{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
