> In HMaster, the checking logic for balancerCutoffTime in buggy.
> See the following code:
> {code:title=HMaster.java|borderStyle=solid}
> 1419 private int getBalancerCutoffTime() {
> 1420 int balancerCutoffTime =
> 1421 getConfiguration().getInt("hbase.balancer.max.balancing", -1);
> 1422 if (balancerCutoffTime == -1) {
> 1423 // No time period set so create one
> 1424 int balancerPeriod =
> 1425 getConfiguration().getInt("hbase.balancer.period", 300000);
> 1426 balancerCutoffTime = balancerPeriod;
> 1427 // If nonsense period, set it to balancerPeriod
> 1428 if (balancerCutoffTime <= 0) balancerCutoffTime = balancerPeriod;
> 1429 }
> 1430 return balancerCutoffTime;
> 1431 }
> {code}
> Basically, the check for "nonsense period" is no effect, because
> balancerCutoffTime is always assigned to be balancerPeriod whatever the value
> is.
