Duo Zhang reassigned HBASE-26235:
---------------------------------
Assignee: Duo Zhang
> We could start RegionServerTracker before becoming active master
> ----------------------------------------------------------------
>
> Key: HBASE-26235
> URL: https://issues.apache.org/jira/browse/HBASE-26235
> Project: HBase
> Issue Type: Sub-task
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> The direct reason is that, after decoupling, HMaster does not extends
> HRegionServer, so we do not have RegionServerAddressTracker now, so for
> backup masters we do not have a way to get all the region server which means
> it can not serve as connection registry any more, so we need to find a way to
> let backup masters to also have a way to get the region server list.
> But in general, since we already have a class in HMaster which is used to
> track region servers, we'd better reuse it. And after this change, the backup
> masters could also be used as the fallback servers for getting region server
> list in HBASE-26220, which could also reduce the load of active master.
