>   <description>Determines where on the local filesystem the DFS name node
>       should store the name table(fsimage).  If this is a comma-delimited list

> In the above property the description part is given as "Determines where on the local
filesystem the DFS name node should store the name table(fsimage).  " but it stores both name
table(If nametable means only fsimage) and edits file.
