Description

The current `locationBudget` is estimated using the `block_replication` in `FileStatus`, which is unreasonable on EC files, because it will count the number of locations of a EC block as 1. We should consider ErasureCodingPolicy of the files to keep the meaning of `locationBudget` consistent.
