Wei-Chiu Chuang commented on HDDS-4327:
---------------------------------------
One of them is in the code:
https://github.com/apache/hadoop-ozone/blob/f25418329cfc5d7194c632b72a9617f5bb7a4bb6/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/OzoneManager.java#L3569
Others are mostly in tests.

> Key: HDDS-4327
> URL: https://issues.apache.org/jira/browse/HDDS-4327
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Reporter: Wei-Chiu Chuang
> Priority: Major
>
> there are a number of places in the code where BatchOperation is used but not
> closed. As a best practice, better to close them explicitly.
> I have a stress test code that uses BatchOperation to insert into OM rocksdb.
> Without closing BatchOperation explicitly, the process crashes after just a
> few minutes.
