                 URL: https://issues.apache.org/jira/browse/HDFS-12033
             Project: Hadoop HDFS

    Affects Versions: 3.0.0-alpha3
            Reporter: Lei (Eddy) Xu

In {{DatanodeManager#handleHeartbeat}}, it choose both pending replication list and pending EC list to up to {{maxTransfers}} items.

It should only send {{maxTransfers}} tasks combined to DN.
