Subject [jira] [Commented] (HADOOP-8139) Path does not allow metachars to be escaped
Date Mon, 12 Mar 2012 21:08:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13227897#comment-13227897

Suresh Srinivas commented on HADOOP-8139:

bq. This should be coordinated with HADOOP-8079, no?
Why? Once the decision is made to support only / based paths, HADOOP-8079 will work also with
that path format right?

Given that this is a blocker for 0.23, and can cause accidental deletion of data, we need
to fix this ASAP. I propose going with earlier solution proposed by Daryn - substituting "\\"
with "/", only if it is Windows. Given that this is an incomplete fix, lets do this change
in a new jira. We could keep this jira open for more complete solution/testing.

> 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.
