> TestBackupNode#testCheckpointNode fails because the following code in FSN#startActiveServices NPEs (resulting in a System.exit) because editLogTailer is set when starting standby services and if ha is not enabled we go directly to the active state. Looks like it should be wrapped with an haEnabled check.
> {code}
> LOG.info("Catching up to latest edits from old active before " +
>    "taking over writer role in edits logs.");
> editLogTailer.catchupDuringFailover();
> {code}
