ASF subversion and git services commented on ACCUMULO-2899:
-----------------------------------------------------------

Commit 31aea2ad89b9b988995a9b8f9096091788eead74 in accumulo's branch refs/heads/1.6.1-SNAPSHOT
from [~busbey]
[ https://git-wip-us.apache.org/repos/asf?p=accumulo.git;h=31aea2a ]

ACCUMULO-2899 Correctly handle older internals.

Make sure that we behave correctly when our cluster has been upgraded 1.4 -> 1.5 ->
1.6

* dfsloggers need to track the cq used to create them so they can be used to issue putDeletes
* rewrite 1.4 WAL paths to the top level wal directory
* adjust recovery path to compensate for 1.4 recovered wals
* fix GC to properly handle upgraded WALs

>    Affects Versions: 1.6.0

>
> After doing a 1.4 -> 1.5 -> 1.6 upgrade that still has WALs for some tables, the
1.6 instance fails to correctly handle the 1.4 recovered WALs.
> This can happen either through not waiting long enough after the upgrade to 1.5 or because
of an offline table brought online on 1.6 (ala ACCUMULO-2816).
