Sanjay Radia commented on HADOOP-8957:
--------------------------------------
bq. Since RawLocalFileSystem doesn't enforce this [isValidName] ..
You are right - lets keep RawLocalFs consistent with RawLocalFileSystem.
RawLocalFileSystem does allow ':' in path - bin/hadoop fs -mkdir /tmp/x:foo
succeeds on a mac.
(Sorry to ask you to change your patch - it was correct). We can file a
separate jira if we want to enforce this.
+1 on the patch modulo the following
* change RawLocalFs to return true as in your previous patch . Add comment that
we rely on OS checking and that RawLocalFs is consistent with
RawLocalFileSystem.
* viewfs#isValidName update comment:
// Prefix validated at mount time and rest of path validated by mount
target.
> AbstractFileSystem#IsValidName should be overridden for embedded file systems
> like ViewFs
