@manishgupta88 but the problem is, if we give multiple location, then spark
may run multiple tasks in one node, which is bad for load performance. i
checked with spark guy, he said that because partitions are few, while cores
are many, so the case that multiple tasks in one node is easy to happen.
Furthermore, considering that the case you mentioned is rare, why not give
only one location ?
