BELUGA BEHR created HDFS-14287:
----------------------------------
Summary: DataXceiverServer May Double-Close
Key: HDFS-14287
URL: https://issues.apache.org/jira/browse/HDFS-14287
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 3.2.0
Reporter: BELUGA BEHR
Attachments: HDFS-14287.1.patch
When a call to [HDFS-14258], when a user calls the {{kill()}} method, it closes
the {{PeerServer}}. This causes the thread reading from the {{PeerServer}} to
interrupt and exit. On the way out, this thread also closes the {{PeerServer}}
for good measure. I'm not sure what the affects of closing the {{PeerServer}}
are twice, but it should be avoided.
To be clear, this is not a regressions caused by [HDFS-14258], if anything,
[HDFS-14258] makes it easier to fix. :)
