Sean Busbey commented on HBASE-11158:
-------------------------------------

It looks like the upgrade command no longer exists.

{code}
Busbey-MBA:hbase-2.0.0-alpha4 busbey$ ./bin/hbase upgrade -h
This command was used to upgrade to HBase 0.96, it was removed in HBase 2.0.0.
Please follow the documentation at http://hbase.apache.org/book.html#upgrading.
{code}

close this out?

>          Issue Type: Bug

>
> When upgrading insitu from 0.94 to 0.96 or 0.98 codecs are usually already there in the servers so it's all fine.
> But when doing an upgrade by moving the data from one cluster to a brand new one, compression codecs might be missing.
> bin/hbase upgrade -check will not report any missing codec, but HBase will not be able to start after the upgrade because the codes are missing.
> I think bin/hbase upgrade -check should check the compression codecs configured on the tables and make sure they are available on the new cluster. f not, it should be reported.
