------------------------------

             Summary: should we bypass the RegionLocationFinder#scheduleFullRefresh execution
when master has not initialized
                 Key: HBASE-20768
                 URL: https://issues.apache.org/jira/browse/HBASE-20768
             Project: HBase
          Issue Type: Improvement
          Components: Balancer
            Reporter: chenxu


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
