> I had a user testing an upgrade from 1.4.5 to 1.6.0 (via 1.5.1) and they ended up with
some unrecoverable data.
> Not all of the WALs got copied from local directories to HDFS, and this was not noticed
during the 1.4 to 1.5 upgrade (possibly due to the presence of offline tables, but we're not
sure). After continuing the upgrade to 1.6, and bringing some of the tables back online, we
discovered that we were missing WALs and could not recover them. We found them on local disks.
