Subject [jira] [Commented] (HADOOP-8139) Path does not allow metachars to be escaped
Date Wed, 07 Mar 2012 00:53:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13223878#comment-13223878
] 

Suresh Srinivas commented on HADOOP-8139:
-----------------------------------------

bq. I suspect there are folks who manage to run Hadoop on Windows with Cygwin today that such
a change would break. This would be a regression.
I am not sure how your change this addresses comment from Doug. See the comment below.

Here are the scenarios to consider (sorry I do not have access to Windows PC).
# On windows terminal paths use '/' and WINDOWS is true.
# On Cygwin terminal paths use '\' and WINDOWS is (probably) true. In this case the patch
might introduce unnecessary behavior?

> Path converts "\" into "/", probably for windows support?  This means it's impossible
for the user to escape metachars in a path name.  Glob expansion can have deadly results.
> Here are the most egregious examples. A user accidentally creates a path like "/user/me/*/file".
 Now they want to remove it.
> {noformat}"hadoop fs -rmr -skipTrash '/user/me/\*'" becomes...
> "hadoop fs -rmr -skipTrash /user/me/*"{noformat}
> * User/Admin: Nuked their home directory or any given directory
> {noformat}"hadoop fs -rmr -skipTrash '\*'" becomes...
> "hadoop fs -rmr -skipTrash /*"{noformat}
> * User:  Deleted _everything_ they have access to on the cluster
> * Admin: *Nukes the entire cluster*
> Note: FsShell is shown for illustrative purposes, however the problem is in the Path
object, not FsShell.
