> In this scenario, regardless of what we do, there will be dataloss unless the correct WAL directory is (again) specified. In fact, I don't believe you can change WAL dir without restarting servers (I also don't think it works with rolling restart). I don't think this is a valid scenario for this issue. No, there will be silent data loss, the user will notice that no region is online, and the cluster is not in a good state, just the same as what you described here. And again, this is not a normal operation in HBase, we do not expect that the WAL directories can be removed without SCP. I wonder why our SCP can even pass without a WAL directory. We should hang there I suppose. Only HBCKSCP can do the dangerous operation. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
