> Key: HBASE-19843
> URL: https://issues.apache.org/jira/browse/HBASE-19843
> Project: HBase
> Issue Type: Sub-task
> Reporter: Duo Zhang
> Priority: Major
>
> If the remote cluster is broken and we want to downgrade the local cluster to
> not write WAL to remote cluster, we need to reopen the region to switch back
> to use the normal WAL.
> But we need to flush before reopening a region, and the flush need to write a
> flush marker to WAL. Since the WAL has already been broken, this can not be
> done...
