[jira] [Commented] (HADOOP-12371) Add a force option for hdfs dfs -expunge to remove all check points

    [ https://issues.apache.org/jira/browse/HADOOP-12371?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14726862#comment-14726862 ] 

Xiaoyu Yao commented on HADOOP-12371:
-------------------------------------

Why not using existing cmd to achieve that, e.g., 'hdfs dfs -rm -r /user/foo/.Trash' ? 
Or using '-skipTrash' in your jobs to avoid putting it in trash at all.
