Hi, I am trying to change the mapping of partitions to workers in
createInitialPartitionOwners(Collection<WorkerInfo> availableWorkerInfos, int maxWorkers) defined in org.apache.giraph.partition.MasterGraphPartitionerImpl.java. The first argument to this method is the list of available workers and each worker has a task id associated with it. When I am specifying the number of workers as 40, the task id are 1 to 40. I have removed one node from the yarn-cluster by following this answer https://stackoverflow.com/questions/41820759/how-to-separately-specify-a-set-of-nodes-for-hdfs-and-others-for-mapreduce-jobs . After this change, the task ids assigned to the workers are no longer consecutive (e.g. for 40 workers the range of task id is 1- 43). Some task-ids are excluded. Is there any way to get these task ids strictly consecutive? Thanks Ravikant
