-----------------------------------
Summary: DagScheduler should allow running concurrent attempts of
a stage in case of multiple fetch failure
Key: SPARK-20091
URL: https://issues.apache.org/jira/browse/SPARK-20091
Project: Spark
Issue Type: Improvement
Components: Scheduler
Affects Versions: 2.0.1
Reporter: Sital Kedia
Currently, the Dag scheduler does not allow running concurrent attempts of a
stage in case of multiple fetch failure. As a result, in case of multipe fetch
failures are detected, serial execution of map stage delays the job run
significantly.
