             Summary: EC: Fix locationBudget in getListing()
                 Key: HDFS-16986
                 URL: https://issues.apache.org/jira/browse/HDFS-16986
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Shuyan Zhang


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.
