Normalizer exits without normalizing all the tables

Currently if there are multiple tables to normalize, normalizer is exiting even before iterating all the table if there is a table that doesnot require normalization

here is the offending code

https://github.com/apache/hbase/blob/branch-1/hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java#L1736

List<NormalizationPlan> plans = this.normalizer.computePlansForTable(table);   
if (plans == null || plans.isEmpty()) {
   return true;
} 

this is running inside loop over tables
