Inter-cluster replication is one of the major targets of 0.21.
For now, you can either do MapReduce exports/imports of your data, or do hdfs-level copies manually or with distcp.

Hi, Is it possible to move hbase/hadoop data from one cluster to another? I have two small clusters, one is for making index tables and another for querying by users. These 2 clusters may have different hardwares but the same softwares (e.g. hadoop 0.19.1 and hbase 0.19.3). Can I sync or scp the data from the first cluster to the second one directly? If I can't do so, is there any simple way to do this? Any suggestion or guide would be appreciate! stchu
