Ru Xiang created SPARK-18607:
--------------------------------
Summary: give a result on a percent of the tasks succeed
Key: SPARK-18607
URL: https://issues.apache.org/jira/browse/SPARK-18607
Project: Spark
Issue Type: New Feature
Components: Spark Core
Reporter: Ru Xiang
In this patch, we modify the codes corresponding to runApproximateJob so that
we can get a result when the specified percent of tasks succeed.
In a production environment, 'long tail' is a common urgent problem. In
practice, as long as we can get a specified percent of tasks' results, we can
guarantee the final results. And this is a common requirement in the practice
of machine learning algorithms.
