> 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.
