HBase should give actionable information when a region is compressed with a
codec that is not available.

Key: HBASE-4458
URL: https://issues.apache.org/jira/browse/HBASE-4458
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.
