obviated by removal of NamespaceUpgrade in HBASE-12623.
> WALFactory use in upgrade path must clean up properly
> -----------------------------------------------------
>
> Key: HBASE-12612
> URL: https://issues.apache.org/jira/browse/HBASE-12612
> Project: HBase
> Issue Type: Bug
> Components: wal
> Affects Versions: 2.0.0
> Reporter: Sean Busbey
> Priority: Blocker
> Fix For: 2.0.0
>
>
> The namespace upgrade code from pre-0.96 requires a clean shutdown prior to
> run. Right now the NamespaceUpgrade code does the following
> # instantiate wal factory
> # ask for a meta-wal
> # online meta and make changes
> # clean up meta-wal
> That last bit is done instead of closing the factory itself. Since the
> factory initializes a non-meta-wal as a part of its constructor, not closing
> it leaves behind an empty wal. The rest of hte upgrade process sees that
> empty wal as an indicator that there's been a failure and goes into recovery.
> The recovery process skips the loading of the hbase:acl table, which then
> causes the upgrade after master initialization to fail.
