> In map() method of GenerateDistCacheData job of Gridmix, val.setSize() is
> done every time based on the bytes to be written to a distributed cache file.
> When we try to write data to next distributed cache file in the same map
> task, the size of random data generated in each iteration can become small
> based on the particular case. This can make this dist cache data generation
> slow.
