Hi, You can take a look at replication. Activate replication from a date X and then copy table from date 0 to date x from the origin to the dest cluster.
You can also export the snapshot. Take a look at 15.8.8 here: http://hbase.apache.org/book/ops.snapshots.html JM 2014-04-02 7:23 GMT-04:00 R W <[email protected]>: > Hi Esteban > > I checked the snapshot feature and tried myself, it's very good, one of the > introduction > > http://blog.cloudera.com/blog/2013/03/introduction-to-apache-hbase-snapshots/mentioned > about: > > Clone a snapshot: This operation creates a new table using the same schema > > and with the same data present in the specified snapshot.
