[jira] [Updated] (HBASE-25517) Reduce race conditions between
balanceRSGroup and balance() cluster, and support concurrently balance
RSGroups
[ https://issues.apache.org/jira/browse/HBASE-25517?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xiaolin Ha updated HBASE-25517:
-------------------------------
Description:
When we call balanceRSGroup(), it waits for the lock of balancer, which may be occupied by the overall cluster balance(). Sometimes the balance of cluster will take a long time because it need to compute the costs or act the balance region plans.
In RSGroup, we don't need to block a balance of one group due to other group balances.
All group are mini clusters, and the balance of their regions should support concurrently execution and reduce the race conditions between them.
