Re: [Condor-users] Steering Jobs to a File on HDFS

Hi Experts,

I see activities of using HDFS as the underlying FS for Condor. As far as I understand condor is copying the file out of HDFS before a job runs, is this correct?

Since HDFS can be exported to workloads (jobs) directly via e.g. Fuse. I am just wondering is it possible that, in a condor cluster where compute worker nodes are also HDFS storage nodes, condor can send the job directly to the node where the file is located on HDFS?

Hi Developers,

In the 2009 what't new in Condor talk ( http://www.cs.wisc.edu/condor/CondorWeek2009/condor_presentations/tannenba_roadmap_2009.ppt ), page 32, it is said:

"Thinking about how Condor can steer jobs to the data
Via a ClassAd function used in the RANK _expression_?"

Just wondering is this done now? If yes is there documentations on how to do it?

Thanks a lot!
