Sameer Paranjpye resolved HADOOP-332. ------------------------------------- Resolution: Duplicate Duplicate of HADOOP-90 > Implement remote replication of dfs namespace images and transaction logs > ------------------------------------------------------------------------- > > Key: HADOOP-332 > URL: http://issues.apache.org/jira/browse/HADOOP-332 > Project: Hadoop > Issue Type: Improvement > Components: dfs > Affects Versions: 0.4.0 > Reporter: Owen O'Malley > Assigned To: Konstantin Shvachko > > The namespace information (image and transaction logs) needs to be replicated > on hosts other than the namenode to prevent data loss if a namenode crashes. > In the short term we will add a new protocol to the datanodes to receive and > store the namespace information. > In the long term, it would be nice to have read-only namenodes that could > receive the information and serve it up for users that want to read data, but > do not need to write to the namespace. -- 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
