nwangtw opened a new pull request #3251: Check invalid number of container in 
round robin packing algorithm
URL: https://github.com/apache/incubator-heron/pull/3251
 
 
   Currently if number of containers is set to an invalid value, we get the 
following exception which is not ideal.
   
   ```
   
   [2019-04-29 15:17:05 -0700] [FINE] org.apache.heron.scheduler.SubmitterMain: 
Exception when submitting topology 
   java.lang.NullPointerException
        at 
org.apache.heron.packing.roundrobin.RoundRobinPacking.getRoundRobinAllocation(RoundRobinPacking.java:385)
        at 
org.apache.heron.packing.roundrobin.RoundRobinPacking.packInternal(RoundRobinPacking.java:149)
   
   ```
   
   After the change, we would expect "Invlaid number of container: %d" runtime 
exception.
