eric baldeschwieler commented on HADOOP-56: ------------------------------------------- A format command sounds useful. GUID and other extensions to block meta data to allow more error checking also sound like a good idea, but I feel like we need to thrash out the use cases Not sure I follow the intended behavior in bryan's example. Maybe we should fork that discussion into an enhancement proposal? > hadoop nameserver does not recognise ndfs nameserver image > ---------------------------------------------------------- > > Key: HADOOP-56 > URL: http://issues.apache.org/jira/browse/HADOOP-56 > Project: Hadoop > Type: Bug > Components: dfs > Versions: 0.1 > Reporter: Yoram Arnon > Priority: Critical > Attachments: ndfs.tar.gz > > hadoop nameserver does not recognise ndfs image > Thus, upgrading from ndfs to hadoop dfs results in total data loss. > The upgrade should be seemless, with the new server recognising all previous > version that are not end-of-life'd. -- 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
