Can someone with the correct privileges make Michele a contributor and reassign this issue?

> The following configuration causes problems:
> <property>
>   <name>dfs.data.dir</name>
>   <value>/mnt/hstore2/hdfs, /home/foo/dfs</value>  
>   <description>
>   Determines where on the local filesystem an DFS data node  should store its bl
> ocks.  If this is a comma-delimited  list of directories, then data will be stor
> ed in all named  directories, typically on different devices.  Directories that 
> do not exist are ignored.  
>   </description>
> </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.
> My proposed solution would be to trimLeft all path names from this and similar property
after splitting on comma.  This still allows spaces in file and directory names but avoids
this problem.
