Anoop Sam John commented on HBASE-26337: ---------------------------------------- When we dont care/consider the locality aspect (Cloud storage so locality will be 0), we can make it not to pick the LocalityCandidateGenerator at all? The cost is configured as 0 already. Same case when we dont use Region replica feature at all. Corresponding costs are already 0. > Optimization for weighted random generators > ------------------------------------------- > > Key: HBASE-26337 > URL: https://issues.apache.org/jira/browse/HBASE-26337 > Project: HBase > Issue Type: Improvement > Components: Balancer > Reporter: Clara Xiong > Assignee: Clara Xiong > Priority: Major > > Currently we use four move candidate generators and pick one randomly for > every move with even probability, all with optimization associated with a > certain group of cost functions. We can assign weight for the random picking > of generators based on balancing pressure on each group. -- This message was sent by Atlassian Jira (v8.20.1#820001)
