             Summary: Make the cost functions optional for StochastoicBalancer
                 Key: HBASE-25006
                 URL: https://issues.apache.org/jira/browse/HBASE-25006
             Project: HBase
          Issue Type: Improvement
            Reporter: Clara Xiong


StochastoicBalancer takes a long time to generate a plan for larger clusters. We want to make the cost functions optional.
hbase.master.balancer.stochastic.regionCountCost: 0
hbase.master.balancer.stochastic.primaryRegionCountCost: 0
hbase.master.balancer.stochastic.tableSkewCost: 0
hbase.master.balancer.stochastic.rackLocalityCost:0
hbase.master.balancer.stochastic.readRequestCost: 0

hbase.master.balancer.stochastic.storefileSizeCost: 0
hbase.master.balancer.stochastic.regionReplicaRackCostKey: 0
hbase.master.balancer.stochastic.serverLocalityCost:0
 
This will turn off all cost functions
To keep some of them, we just need to set some to positive value
