Subject [jira] [Commented] (HDFS-11279) Cleanup unused DataNode#checkDiskErrorAsync()
Date Tue, 03 Jan 2017 20:45:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15796134#comment-15796134

Xiaoyu Yao commented on HDFS-11279:
-----------------------------------

Thanks [~hanishakoneru] for the update.  +1 pending Jenkins. 
There is a unused import in DataNode.java which we can fix at commit time to save a Jenkins
run.

> After HDFS-11274, we will not trigger checking all datanode volumes upon IO failure on
a single volume. This makes the original 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.
