-----------------------------------
Shall we file a separate jira for updating the release doc? [~jojochuang]

> -----------------------------------
>
> Key: HDFS-14595
> URL: https://issues.apache.org/jira/browse/HDFS-14595
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.2.0, 3.1.2
> Reporter: Wei-Chiu Chuang
> Assignee: Siyao Meng
> Priority: Blocker
> Attachments: HDFS-14595.001.patch, hadoop_ 36e1870eab904d5a6f12ecfb1fdb52ca08d95ac5 to b241194d56f97ee372cbec7062bcf155bc3df662 compatibility report.htm

>
> Our internal tool caught an API compatibility issue with HDFS-11848.
> HDFS-11848 adds an additional parameter to DistributedFileSystem.listOpenFiles(), but it doesn't keep the existing API.
> This can cause issue when upgrading from Hadoop 2.9.0/2.8.3/3.0.0 to 3.0.1/3.1.0 and above.
> Suggest:
> (1) Add back the old API (which was added in HDFS-10480), and mark it deprecated.
> (2) Update release doc to enforce running API compatibility check for each releases.
