niuyulin created HBASE-23944:
--------------------------------

             Summary: The method setClusterLoad of SimpleLoadBalancer is incorrect when balance by table 
                 Key: HBASE-23944
                 URL: https://issues.apache.org/jira/browse/HBASE-23944
             Project: HBase
          Issue Type: Bug
          Components: Balancer
    Affects Versions: 2.2.2
            Reporter: niuyulin
            Assignee: niuyulin
             Fix For: 3.0.0, 2.2.2


now if in parameter clusterLoad is by table, for example
{code:java}
table1=>
     server1=>[table1,region1]
     server2=>[]
table2=>
    server1=>[table2,region1]
    server2=>[]
{code}
then, the member variable serverLoadList is:
{code:java}
[{server1, load 1}{server2, load 0}{server1, load 1} {server2, load 0}]
{code}
the cluster will be considered balanced  in method overallNeedsBalance
