> It's a bug on 0.5.0 after migration of
> [TUBEMQ-126|https://issues.apache.org/jira/projects/TUBEMQ/issues/TUBEMQ-126]:
> broker would disappear after updating its default metadata on
> unflushDataHold, which resulting an "out-of-sync" issue on metadata
> management.
> Reproduce steps:
> # Bring a broker online;
> # Use webapi to submit an update about type of
> "admin_update_broker_configure", setting a new unflushDataHold;
> # Monitor log, it would successfully fire this event and proceed the update;
> # Refresh the broker list on master, you will find it's disappeared;
> # Retry to add the broker with the same BrokerID and IP Address, it would
> raise an error about duplicated configuration found, but the broker is still
> unseen in the broker list.
> Bug is relating to BDB and Master initialization and meta-replication
> routines.
