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.
