Migration

Hi,
     Incase we migrate from hadoop 0.19.0 and hbase 0.19.0 to hadoop 0.20.0
and hbase 0.20.0 respectively, how would it affect the existing data on
hadoop dfs and hbase tables? can we migrate the data using distcp only??

Regards
Raakhi

Hi Rakhi!
Not exactly sure how the migration tool is going to look for 0.20 but the
whole disk storage format
is going to change so I don't think that you will be able to just use
distcp.
