Hitesh Shah commented on TEZ-2800:
----------------------------------
You dont need to use a map.
Consider vertex v1 (idx=0) having 100 tasks and v2 (idx=1) having 250 tasks.
Assuming no filtering/sorting, if 75 tasks are requested at a time, a simple
algo would be to:
- pick vertex ( idx=0 ), get tasks from id 0 to 74
- next, call pick vertex idx 1, start from 75 to numTasks are hit. Move to
vertex idx 1 and get remaining tasks ...
Vertex ids do not change - neither do task ids. Yes - there can be new tasks
created between the first and second calls but that is ok.
