-------------------------------------
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.
