stack commented on HBASE-4458:
------------------------------
So HBASE-2514 didn't work? Or, wasn't used I suppose. Here is doc on lzo:
http://hbase.apache.org/book.html#lzo.compression It wasn't followed? I agree
it'd be better having issue show on master UI if we can.
> HBase should give actionable information when a region is compressed with a
> codec that is not available.

> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.90.3
> Reporter: Jonathan Hsieh
>
> A cluster that previously used LZO codec was upgraded with the intent of
> moving away from the codec to another. Several regions failed to deploy
> because the LZO codec was no longer present. However, there was little
> indication that this as the problem.
> Ideally, the master web ui or hbck would detect these problems and provide
> why it fails to deploy and also provide an actionable error message.
