> bq. Server failure. HBase can still read HFiles written in the older version
> 2 format.
> Need a script that user can run pre-upgrade.
> {quote}
> Additional commentary from [~busbey]
> In addition to the config check stack mentions, such a tool could check
> * other problematic configs, like those for master-hosts-regions
> * inconsistent configs due to changed defaults (I think we should have some
> smell-tests around the change in default for hbase.security.authorization)
> * (optionally) check for unreadable WALs
> * (optionally) check for unreadable hfiles
