             Summary: Add a protocol command from NN to DN for dropping the SPS work and queues 
                 Key: HDFS-11243
                 URL: https://issues.apache.org/jira/browse/HDFS-11243
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode, namenode
            Reporter: Uma Maheswara Rao G
            Assignee: Uma Maheswara Rao G


This JIRA is for adding a protocol command from Namenode to Datanode for dropping SPS work. and Also for dropping in progress queues.

Use case is: when admin deactivated SPS at NN, then internally NN should issue a command to DNs for dropping in progress queues as well. This command can be packed via heartbeat.
