Biju Nair commented on HBASE-20768:
-----------------------------------
{noformat}
+ // Do not scheduleFullRefresh at master startup
{noformat}
The comment is from HBASE-16570 and looks like no regression. Can we merge this
change? [~apurtell], [~mdrob]
> should we bypass the RegionLocationFinder#scheduleFullRefresh execution when
> master has not initialized

> Our KYLIN cluster has about 300K Regions, when master startup, It takes a
> long time to do RegionLocationFinder#scheduleFullRefresh.
> During this period, CUBE cannot be built, because master has not initialized.
> Although we can ignore locality factor through HBASE-18478, but i think it
> would be better if we bypass the RegionLocationFinder#scheduleFullRefresh
> until the master initialized
