there is no good idea for your question. but for hadoop-2.x, its easy with HDFS federation.

Hey Guys,
I have two different hadoop clusters in production. One cluster is used as backing for HBase and the other for other things. Both hadoop clusters are using the same version 1.0 and I want to merge them and make them one. I know, one possible solution is to copy the data across, but the data is really huge on these clusters and it will hard for me to compromise with huge downtime.
Is there any optimal way to merge two hadoop clusters.
