[Gridmix] GenerateDistCacheData job of Gridmix can become slow in some cases
----------------------------------------------------------------------------
Key: MAPREDUCE-4087
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4087
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Ravi Gummadi
Assignee: Ravi Gummadi
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.
