Hadoop should include a general purpose distributed lock manager
----------------------------------------------------------------

                 Key: HADOOP-727
                 URL: http://issues.apache.org/jira/browse/HADOOP-727
             Project: Hadoop
          Issue Type: New Feature
          Components: ipc
            Reporter: Sameer Paranjpye
            Priority: Minor


Related to HADOOP-726. Currently, there is no good way for distributed apps using HDFS or
Map/Reduce to synchronize their operations. HDFS locking doesn't work very well and lock management
is an unnecessary burden on the namenode. In addition, it depending on the filesystem for
locking could make applications less portable. Hadoop should implement a general purpose distributed
lock management service.
