---------------------------------
Summary: Make LoadBalancer not extend Configured interface
Key: HBASE-25851
URL: https://issues.apache.org/jira/browse/HBASE-25851
Project: HBase
Issue Type: Sub-task
Environment: M
Reporter: Duo Zhang
Fix For: 3.0.0-alpha-1, 2.5.0
On master, LoadBalancer has a setClusterInfoProvider method and on branch-2,
LoadBalancer has a setMasterServices method. Both ClusterInfoProvider and
MasterServices could give a Configuration out so I do not think we need to
expose another setConf method.
When refactoring StochasticLoadBalancer, the initialization order is also a
pain as after setConf, we will load a lot of configuration but at that time,
the ClusterInfoProvider is not present, and easy to cause NPE...
And it could also help simplity locking.
