Ted Yu commented on HBASE-18051:
--------------------------------

HBaseAdmin has the following method:
{code}
  public boolean isBalancerEnabled() throws IOException {
{code}
MasterRpcServices has:
{code}
  public IsBalancerEnabledResponse isBalancerEnabled(RpcController controller,
      IsBalancerEnabledRequest request) throws ServiceException {
    IsBalancerEnabledResponse.Builder response = IsBalancerEnabledResponse.newBuilder();
    response.setEnabled(master.isBalancerOn());
{code}
See if you can utilize existing method(s) and not add isBalancerOn() to MasterServices

> balance_rsgroup still run when the Load Balancer is not enabled.

> When the Load Balancer is not enabled, the command "balancer" will not be executed , but the command "balance_rsgroup" can still run, which is not reasonable.So we need to fix it
