Subject Hbase / How to Migrate
Date Wed, 30 Jul 2014 20:41:48 GMT
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?

Here is my version information:
