Subject [jira] [Created] (HIVE-9234) HiveServer2 leaks FileSystem objects in FileSystem.CACHE

--------------------------------------

             Summary: HiveServer2 leaks FileSystem objects in FileSystem.CACHE
                 Key: HIVE-9234
                 URL: https://issues.apache.org/jira/browse/HIVE-9234
             Project: Hive
          Issue Type: Bug
            Reporter: Vaibhav Gumashta
            Assignee: Vaibhav Gumashta


Running over extended period (48+ hrs), we've noticed HiveServer2 leaking FileSystem objects
in FileSystem.CACHE. Linked jiras were previous attempts to fix it, but the issue still seems
to be there. A workaround is to disable the caching (by setting {{fs.hdfs.impl.disable.cache}}
and {{fs.file.impl.disable.cache}} to {{true}}), but creating new FileSystem objects is expensive.
