I am following this article to tune the cluster and its stating a parameter "dfs.data.dirs" , I don't see it in my system ?
@Sami Ahmad, It looks like the document used an older property name.
You should look for dfs.datanode.data.dir property instead dfs.data.dirs. ( dfs.data.dirs property was renamed to be dfs.datanode.data.dir in Hadoop2)
