[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. -- This message is automatically generated by JIRA.
