>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: snapshots

> There are a number of restrictions on valid names in HDFS. For example, you can't name a directory "." or "..", or something containing a ":".
> However, I can happily create a snapshot named "a:b:c", resulting in this:
> {code}
> -> % hdfs dfs -createSnapshot /home/andrew a:b:c
> Created snapshot /home/andrew/.snapshot/a:b:c
> -> % hadoop fs -ls /home/andrew/.snapshot
> -ls: java.net.URISyntaxException: Relative path in absolute URI: a:b:c
> Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]
> {code}
