---------------------------------
Summary: Revisit the synchronization of balancer implementation
Key: HBASE-25826
URL: https://issues.apache.org/jira/browse/HBASE-25826
Project: HBase
Issue Type: Improvement
Reporter: Duo Zhang
In StochasticLoadBalancer, some methods are synchronized, for example,
setClusterMetrics, setConf, balanceTable, etc.
What I can see is that, we have ConfigurationObserver support, so we need to
make sure that the configuration updating does not effect the balance
operation, so we need synchronization here. But do we support two balance
operations at the same time? And what about other balancer implementations?
I think we need to make the synchronization more clearer.
