RegionLocationFinder#scheduleFullRefresh execution when master has not
initialized
chenxu created HBASE-20768:
------------------------------
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
