> TestFileAppend3 fails intermittently in the branch. The issue is that
> FSDataset#recoverCheck calls getReplicaInfo which also matches the generation
> stamp during pipeline recovery. The fix is to make sure generation stamp is
> not checked while replica lookup in this case as it is done in the trunk
> code. The generation stamp check is done later in recoverCheck method.
