Duo Zhang commented on HBASE-27982:
-----------------------------------
At xiaomi, for support hadoop 2.6 or 2.4, I changed the implementation to not
rely on truncate API, it is possible. If this is also a problem here I could
try to remember how I did this and implement it in the open source version.
Thanks.

> Ok. I missed this but I was just told that the synchronous replication

> 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.
