[jira] [Created] (HDFS-5501) Fix pendingReceivedRequests tracking in BPServiceActor

Arpit Agarwal created HDFS-5501:
-----------------------------------

             Summary: Fix pendingReceivedRequests tracking in BPServiceActor
                 Key: HDFS-5501
                 URL: https://issues.apache.org/jira/browse/HDFS-5501
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode
    Affects Versions: Heterogeneous Storage (HDFS-2832)
            Reporter: Arpit Agarwal
            Assignee: Arpit Agarwal


{{BPServiceActor#pendingReceivedRequests}} is not tracked correctly for multiple storages. Previously this counter was treated more like a flag, i.e. we only cared whether it was zero or greater than zero. With multiple storages we need to be more precise in tracking this value to correctly determine when to generate incremental block reports.
