> Ok. I missed this but I was just told that the synchronous replication
> leverages the truncate() FS API.
> https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/master/replication/SyncReplicationReplayWALManager.java#L282
> Ozone does not implement truncate so calling this method on the WAL FS will
> result in an exception. It would be a better user experience to alert user
> that this is not supported from the start.
