> Key: SPARK-2557
> URL: https://issues.apache.org/jira/browse/SPARK-2557
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.0.0
> Reporter: Ye Xianjin
> Priority: Minor
> Labels: starter
> Fix For: 1.1.0
>
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> In SparkContext.createTaskScheduler, we can use {code}local[*]{code} to
> estimates the number of cores on the machine. I think we should also be able
> to use * in the local-n-failures mode.
> And according to the code in the LOCAL_N_REGEX pattern matching code, I
> believe the regular expression of LOCAL_N_REGEX is wrong. LOCAL_N_REFEX
> should be
> {code}
> """local\[([0-9]+|\*)\]""".r
> {code}
> rather than
> {code}
> """local\[([0-9\*]+)\]""".r
> {code}
