Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The following page has been changed by JimKellerman: http://wiki.apache.org/hadoop/Hbase/Migration The comment on the change is: change wording to avoid text being interpreted as Wiki words ------------------------------------------------------------------------------ == Assertions == - * All hbase data and state is out on the FileSystem: Moving from one version should be just a case of moving or rewriting files on the FileSystem. + * All hbase data and state is out on the file system: Moving from one version should be just a case of moving or rewriting files on the file system. * Hbase cannot be running when a migration is run. * This can be tricky to assert when the hbase versions differ to the extent that they are unable to talk to each other (Caller just hangs and eventually timesout). * Sometimes, the amount of on-filesystem data that needs to be changed will be large so migration will need to run a MR job.
