[jira] [Created] (HBASE-26443) Some BaseLoadBalancer log lines should be at DEBUG level

Andrew Kyle Purtell created HBASE-26443:
-------------------------------------------

             Summary: Some BaseLoadBalancer log lines should be at DEBUG level
                 Key: HBASE-26443
                 URL: https://issues.apache.org/jira/browse/HBASE-26443
             Project: HBase
          Issue Type: Task
    Affects Versions: 2.4.9
            Reporter: Andrew Kyle Purtell
            Assignee: Andrew Kyle Purtell
             Fix For: 2.5.0, 3.0.0-alpha-2, 2.4.9


These are printed per chore run, per host:

[00]2021-11-10 22:07:32,984 INFO  [master/ip-172-31-58-47:8100.Chore.1] balancer.BaseLoadBalancer: Start Generate Balance plan for cluster.
[00]2021-11-10 22:07:32,998 INFO  [master/ip-172-31-58-47:8100.Chore.1] balancer.BaseLoadBalancer: server <N> is on rack <R>

....
One log line per server. On a large cluster, this is a lot of unnecessary logging. 

The 'Start Generate Balance plan for cluster.' log line should be at DEBUG.


The 'server <N> is on rack <R>' log line arguably should be at TRACE. It will never change. It is not interesting unless you are debugging the balancer.
