Subject [jira] [Created] (HDFS-10817) Add Logging for Long-held NN Read Locks
Date Tue, 30 Aug 2016 16:26:21 GMT
Erik Krogen created HDFS-10817:
----------------------------------

             Summary: Add Logging for Long-held NN Read Locks
                 Key: HDFS-10817
                 URL: https://issues.apache.org/jira/browse/HDFS-10817
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: logging, namenode
            Reporter: Erik Krogen
            Assignee: Erik Krogen


Right now the Namenode will log when a write lock is held for a long time to help tracks methods
which are causing expensive delays. Let's do the same for read locks since these operations
may also be expensive/long and cause delays.
