[jira] [Created] (HDFS-11279) Cleanup unused DataNode#checkDiskErrorAsync()

Xiaoyu Yao created HDFS-11279:
---------------------------------

             Summary: Cleanup unused DataNode#checkDiskErrorAsync()
                 Key: HDFS-11279
                 URL: https://issues.apache.org/jira/browse/HDFS-11279
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Xiaoyu Yao
            Priority: Minor


After HDFS-11274, we will not trigger checking all datanode volumes upon IO failure on a single volume. This makes the origin implementation DataNode#checkDiskErrorAsync and  DatasetVolumeChecker#checkAllVolumesAsync() not used in any of the production code. 

This ticket is opened to remove these unused code and related tests if any.
