Hi, I am trying to upgrade from CDH4.5 (which contains Hbase 0.94.6) to CDH5.0 (which contains hbase 0.96). >From Cloudera documentation I found that: "Rolling upgrades from CDH 4 to CDH 5 are not possible because existing CDH 4 HBase clients cannot make requests to CDH 5 servers and CDH 5 HBase clients cannot make requests to CDH 4 servers. Replication between CDH 4 and CDH 5 is not currently supported".
We have 2 clusters in production using replication. The question is how to perform the upgrade on live system, if replication isn't possible from 4.5 to 5.0. Lets assume I will upgrade the non primary cluster to 5.0, while the live cluster will remain the one with 4.5. How can I catch up the data afterwards? Does CopyTable works between 4.5 to 5.0? Is there any compatible tool to do the migration?
