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 stack:
http://wiki.apache.org/hadoop/Hbase/HowToMigrate

------------------------------------------------------------------------------
  Migration does not work for transactional hbase installs or for indexed hbase installs.
 Talk to us if you need this.
  
  This migration rewrites all data.  It will take a while.  TODO: MR version and single-threaded
version. How-to.
+ 
+ It will disable compression setting all column families to no compression.  Enable manually
post-compression (Rare should be person who has compression enabled -- talk to us if this
is a problem).
