Hi, There: I have been evaluating cdh3b3 for a while and noticed 2 major change: 1. the hadoop protocol layer is incompatible with cdh3b2, and data needs to be upgraded. same for hbase. 2. user hdfs and mapred are introduced to replace user hadoop.
I am wondering when the next cdh3 release will come out, and will it be compatible with cdh3b3 ? Since cdh3b2 to b3 migration requires cluster down time , I want to minimize the down time as much as possible. if next cdh3 is compatible with b3, I will upgrade to b3 first and then to next new release. otherwise I will wait for next release . By the way, I found cdh3b3's performance doubles that of cdh3b2 in both hadoop and hbase, and hbase stability drastically improved. Nice job. Jimmy.
