Subject [jira] [Created] (HBASE-11158) bin/hbase upgrade -check should also check compression codecs
Date Tue, 13 May 2014 12:48:15 GMT
Jean-Marc Spaggiari created HBASE-11158:
-------------------------------------------

             Summary: bin/hbase upgrade -check should also check compression codecs
                 Key: HBASE-11158
                 URL: https://issues.apache.org/jira/browse/HBASE-11158
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.99.0
            Reporter: Jean-Marc Spaggiari


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.
