> Improve execution code in CompactingHashTable.java

>             Project: Flink
>          Issue Type: Improvement
>          Components: Local Runtime
>    Affects Versions: 0.10
>            Reporter: Huang Wei
>             Fix For: 0.10
>
>   Original Estimate: 168h
>  Remaining Estimate: 168h
>
> I found some improved code in CompactingHashTable.java since this code will 
> execute many times when flink runs.
> In my opinion, some codes in "for" and "while" can be optimized to reduce the 
> times of execution and it is effective to increase the performance.
> For example, the code following:
> 'while(numBuckets % numPartitions != 0) {
>                       numBuckets++;
>               }'
> can be optimized into a formula:
> numBuckets += numPartitions - (numBuckets % numPartitions);
