Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "Hbase/HowToMigrate" page has been changed by stack. http://wiki.apache.org/hadoop/Hbase/HowToMigrate?action=diff&rev1=41&rev2=42 -------------------------------------------------- == Version-Specific Migration Notes == - <<Anchor(090)>> + <<Anchor(90)>> - === From 0.20.x to 0.90.x (or to 0.89.x) === + === From 0.20.x to 0.90.x (or to 0.89.x) === Nothing special is needed going between the two versions. You should be able to just shutdown your 0.20.x cluster, install 0.90.x (or 0.89.x), REMOVE conf/hbase-default.xml (its now inside the hbase jar; and old 0.20.x hbase-default.xml actually has config damaging to hbase 0.90.x), review hbase-site.xml so it only references config. that is in 0.90.x -- see [[http://hbase.apache.org/configuration.html#hbase_default_configurations|0.90.x hbase-default.xml]] -- and restart.
