Path does not allow metachars to be escaped
-------------------------------------------
Key: HADOOP-8139
URL: https://issues.apache.org/jira/browse/HADOOP-8139
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.23.0, 0.24.0
Reporter: Daryn Sharp
Priority: Blocker
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.
