[jira] [Updated] (HIVE-20979) Fix memory leak in hive streaming
[ https://issues.apache.org/jira/browse/HIVE-20979?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shubham Chaurasia updated HIVE-20979:
-------------------------------------
Description:
{{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
