The following page has been changed by stack: http://wiki.apache.org/hadoop/Hbase/HowToMigrate The comment on the change is: Small additions to Izaak's notes ------------------------------------------------------------------------------ * Shut down the old instance of HBase. * If necessary, upgrade the underlying version of Hadoop to the version required by the new instance of HBase. Refer to the [http://wiki.apache.org/hadoop/Hadoop%20Upgrade Hadoop Upgrade] page. - * Download and configure the new instance of HBase. Make sure you configure the hbase.rootdir of the new instance to be the same as that from the old instance. + * Download and configure the new instance of HBase. Make sure you configure the ''hbase.rootdir'' of the new instance to be the same as that from the old instance. - * From the new instance of HBase, perform the HBase migration. See the version-specific notes below for more specific information on this process. + * From the new instance of HBase, perform the HBase migration. Run ''%{HBASE_HOME}/bin/hbase migrate'' for usage. See the version-specific notes below for more specific information on this process. * Start the new instance of HBase. == Version-Specific Migration Notes == === From 0.1.x to 0.2.x === - HBase 0.1 depends on Hadoop 0.16. HBase 0.2 depends on Hadoop 0.17, and as such you will need to upgrade your version of Hadoop as part of this migration. + HBase 0.1 depends on Hadoop 0.16. HBase 0.2 depends on Hadoop 0.17 so first you will need to upgrade your version of Hadoop as part of this migration. - The actual migration command to be executed by the new HBase 0.2 instance is: + After the hadoop migration is complete, the actual migration command to be executed by the new HBase 0.2 instance is: - {$HBASE_HOME}/bin/hbase migrate update + {{{{$HBASE_HOME}/bin/hbase migrate update}}}
