[ http://issues.apache.org/jira/browse/HADOOP-727?page=comments#action_12450248 ] Runping Qi commented on HADOOP-727: -----------------------------------
If this is for coarse grain locking, then Chubby is a good candidate to implement. > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
