Hi guys ! Q> How can i assign data of each job in mumak nodes and what else i need to do ? In general how can i use the pluggable block-placement for HDFS in Mumak ? Meaning in my context i am using 19-jobs-trace json file and modified topology json file consisting of say 4 nodes. Since the number of tasks(map & reduce) are fixed for these jobs i want to assign the input data( with their replication) of each job to some particular nodes, so that i can use this info in my scheduler . Does the code for "ObtainLocalMapTask" / "ObtainNonlocalMaptask" in Scheduler need to be changed if i have to use this data placement info ?
Q>If i have to add some fields to jobs in job trace file , how do i add it to job trace and access in my scheduler code for scheduling in Mumak. Which classes do i need to modify for this? Thanks, Arun
