[jira] [Commented] (HBASE-27982) Synchronous replication should check if the file system supports truncate API

["Tak-Lon (Stephen) Wu (Jira)" <ji...@apache.org>]

Tak-Lon (Stephen) Wu commented on HBASE-27982:
----------------------------------------------

I guessed based on the PR https://github.com/apache/hbase/pull/5747 , we can close this task and let the exception throws when truncate API wasn't implemented?

> Ok. I missed this but I was just told that the synchronous replication leverages the truncate() FS API.

> 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.
