Subject [jira] [Created] (HDFS-11021) Add FSNamesystemLock metrics for BlockManager operations
Date Mon, 17 Oct 2016 17:33:58 GMT
Erik Krogen created HDFS-11021:
----------------------------------

             Summary: Add FSNamesystemLock metrics for BlockManager operations
                 Key: HDFS-11021
                 URL: https://issues.apache.org/jira/browse/HDFS-11021
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
            Reporter: Erik Krogen
            Assignee: Erik Krogen


Right now the operations which the {{BlockManager}} issues to the {{Namesystem}} will not
emit metrics about which operation caused the {{FSNamesystemLock}} to be held; they are all
grouped under "OTHER". We should fix this since the {{BlockManager}} creates many acquisitions
of both the read and write locks.
