Hello, Corollary, what is the better way to migrate data from a 0.90 cluster to a 0.92 cluser ?
Hbase 0.90 => Client 0.90 => stdout | stdin => client 0.92 => Hbase 0.92 All the data must tansit on a single host where compute the 2 clients. It may be paralalize with mutiple version working with different range scanner maybe but not so easy. Is there a copytable version that should read on 0.90 to write on 0.92 with mapreduce version ? maybe there is some sort of namespace available for Java Classes that we may use 2 version of a same package and go for a mapreduce ?
