> In Jira HDFS-16600. Fix deadlock on DataNode side. We discussed the issue of
> deadlock, this is a very meaningful discussion, I was reading the log and
> found the following:
> {code:java}
> 2022-05-27 07:39:47,890 [Listener at localhost/36941] WARN
> datanode.DataSetLockManager (DataSetLockManager.java:lockLeakCheck(261)) -
> not open lock leak check func.{code}
> Looking at the code, I found that there is such a parameter:
> {code:java}
> <property>
> <name>dfs.datanode.lockmanager.trace</name>
> <value>false</value>
> <description>
> If this is true, after shut down datanode lock Manager will print all
> leak
> thread that not release by lock Manager. Only used for test or trace
> dead lock
> problem. In produce default set false, because it's have little
> performance loss.
> </description>
> </property> {code}
> I think this parameter should be added in the test environment, so that if
> there is a DN deadlock, the cause can be quickly located.
