      Description

      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.
