Mike Drob commented on HBASE-11158:
-----------------------------------

What's the upgrade path, then? I think this is still a good check to have, will 
we just fail on startup currently?

> bin/hbase upgrade -check should also check compression codecs

>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.99.0
>            Reporter: Jean-Marc Spaggiari
>            Priority: Major
>
> 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.
