[jira] Issue Comment Edited: (HADOOP-3173) inconsistent globbing
support for dfs commands
[ https://issues.apache.org/jira/browse/HADOOP-3173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586607#action_12586607 ]

---------------------------------------------------------------
This is a known issue and is not a regression. See HADOOP-1995. So I am not going to mark it a blocker to release 0.17. Code-wise we use backslash to escape glob special characters. But backslash collides with the windows path separator. It does not work.
For now I would suggest a user to programatically remove a directory/file whose name contains glob special characters.
Also Rajiv, you should quote all dfs globs in the command line. Otherwise, the local file system will interpret it first.
