Hi Jon The thing is when you mount a system and the mapred directory is present on the mounted space
it will write to that folder mimicking network writes So you can have this mounted in the task trackers i guess. Am i right guys? The dfs is managing content without having any filesystem in place. It indirectly mimicks a networked file system on top of your existing one. Hope that answers your question. Please correct me if i am wrong Rgds Prabhu On 3/1/06, Jon Blower <[EMAIL PROTECTED]> wrote: > > > > > > Stefan Groschupf wrote: > > > in general > > > hadoop's tasktracks and jobtrackers require to run with a > > switched-on dfs. > > > > Stefan: that should not be the case.
