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.
