upgrade to 0.92 from 0.90.x
Hi:
Is there anyway to upgrade a cluster from 0.90.x to 0.92 without loss
data?
I don't know how to deal with HFileV2 or Response's size(HBASE-3581).

I don't think so.
Cheers

Hi Ted:
Would a 0.92 client be able to talk to a 0.90.x cluster? (i.e. the
other way around?)

HBASE-3581 would disallow 0.90 HBase client to talk to 0.92 HBase server.
So in order to utilize the new cluster, you should upgrade your clients as
well.
I think HFileV2 is able to read V1 HFile and perform conversion.
