>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: data-node, name-node
>    Affects Versions: 0.20.1, 0.21.0
>            Reporter: Michele (aka pirroh) Catasta
>            Priority: Minor
>         Attachments: HDFS-455.patch, hdfs-455.txt

> The following configuration causes problems:
> <property>
> <name>dfs.data.dir</name>
> <value>/mnt/hstore2/hdfs, /home/foo/dfs</value> 
> </property>
> The problem is that the space after the comma causes the second directory for storage
to be " /home/foo/dfs" which is in a directory named <SPACE> which contains a sub-dir
named "home" in the hadoop datanodes default directory. This will typically cause the user's
home partition to fill, but will be very hard for the user to understand since a directory
with a whitespace name is hard to understand.
