             Summary: Datanode to print the blockID while releasing the SCFds
                 Key: HDFS-16580
                 URL: https://issues.apache.org/jira/browse/HDFS-16580
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 3.3.2, 3.1.4, 3.4.0
            Reporter: Renukaprasad C
            Assignee: Renukaprasad C


Method - org.apache.hadoop.hdfs.server.datanode.DataXceiver#requestShortCircuitFds prints the block ID entered for short circuit read, but corresponding entry missing in org.apache.hadoop.hdfs.server.datanode.DataXceiver#releaseShortCircuitFds. 

Its good to have corresponding blockID in release method as well.

We are facing some random file read issues when SCR enabled. It From the current logs, we cannot map request & release flows. 

It will be helpful in debugging issues if we log blockID in release methods as well.
