I'm preparing to migrate an hbase database between clusters, but using the same hbase version 0.92.1-cdh4.1.3. I found the document http://wiki.apache.org/hadoop/Hbase/HowToMigrate had a link to an older document about the design http://wiki.apache.org/hadoop/Hbase/Migration . In that document was the statment:
Sometimes, the amount of on-filesystem data that needs to be changed will be large so migration will need to run a MR job. I am planning on migrating a large HBase database in the near future. Will the /bin/hbase migrate work for migrating a large database, or will it require another method? If so can anybody point me to a reference or give a suggestion?
