Ashu Pachauri created HBASE-17202: ------------------------------------- Summary: Master takes a long time to initialize Key: HBASE-17202 URL: https://issues.apache.org/jira/browse/HBASE-17202 Project: HBase Issue Type: Improvement Components: Balancer, master Reporter: Ashu Pachauri Assignee: Ashu Pachauri
On master failover or a full cluster restart, we create the RegionLocationFinder cache by calculating block locations for every region used by the balancer. This greatly increases the time it takes for the assignment manager to start and affects region availability in scenarios of full cluster restart. We should initialize assignment manager with the bare minimum information and asynchronously load the block location cache. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
