morningman opened a new issue #1580: Load failed when cluster balacing URL: https://github.com/apache/incubator-doris/issues/1580 **Describe the bug** When cluster is doing balance, load process's failure possibility is increasing. Error message shows "xxxx tablet has few replicas" or "tablet writer write failed, res = -215" **To Reproduce** add a new BE to the cluster and start a long time load job. **Expected behavior** Cluster balance should not cause load failed. **Reason** It is because the balance logic is first adding a replica, and then delete a old replica. But when deleting the old replica, it does not consider the load job on that replica, so the load job may failed to find the replica because the replica is already being deleted.
