Upgrade from 0.90.1 to 0.90.2/3

[Weiwei Xiong <xi...@gmail.com>]

Hi all,

I am currently using hbase 0.90.1 but got an issue same as HBASE-3660. It
seems this problem has been solved in 0.90.2. So I want to upgrade to it.

The question is, can I safely upgrade to 0.90.2/3 from 0.90.1 by replacing
the whole HBASE package with the newer one? I am really concerned if it
might break the metadata and I can't even go back to 0.90.1 once I tried.

Thanks,
-- ww

Thanks for your info J-D.

My problem is a little different. My HBase master just can't start now
because of the IP change. I guess I can't do a rolling start in this
case. So I am wondering if I could just pull 0.90.2/3 and start all
hbase daemons on the existing hbase tables.

Thanks,

All minor versions are compatible between them, you can do a rolling
upgrade if you want:
http://hbase.apache.org/book/decommission.html#rolling

All you need to add is a step where you replace the distribution
before restarting the process.
