--------------------------------------
Summary: SplitSampler in mapreduce.lib should use a SPLIT_STEP to
jump around splits
Key: MAPREDUCE-5225
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5225
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Zhijie Shen
Assignee: Zhijie Shen
Now, SplitSampler only samples the first maxSplitsSampled splits, caused by
MAPREDUCE-1820. However, jumping around all splits is in general preferable
than the first N splits.
