---------------------------------
Summary: HDFSCleanup thread holds reference to FileSystem
Key: HIVE-8914
URL: https://issues.apache.org/jira/browse/HIVE-8914
Project: Hive
Issue Type: Bug
Components: WebHCat
Affects Versions: 0.13.1
Reporter: shanyu zhao
Assignee: shanyu zhao
WebHCat server has a long running cleanup thread (HDFSCleanup) which holds a
reference to FileSystem. Because of this reference, many FileSystem related
objects (e.g. MetricsSystemImpl) cannot be garbage collected. Sometimes this
causes OOM exception. Since the cleanup is done every 12 hours by default, we
can simply recreate a FileSystem when we need to use it.
