Apache Spark reassigned SPARK-17675:
------------------------------------
Assignee: Imran Rashid (was: Apache Spark)
> Add Blacklisting of Executors & Nodes within one TaskSet
> --------------------------------------------------------
>
> Key: SPARK-17675
> URL: https://issues.apache.org/jira/browse/SPARK-17675
> Project: Spark
> Issue Type: Task
> Components: Scheduler
> Affects Versions: 2.0.0
> Reporter: Imran Rashid
> Assignee: Imran Rashid
>
> This is a step along the way to SPARK-8425 -- see the design doc on that jira
> for a complete discussion of blacklisting.
> To enable incremental review, the first step proposed here is to expand the
> blacklisting within tasksets. In particular, this will enable blacklisting
> for
> * (task, executor) pairs (this already exists via an undocumented config)
> * (task, node)
> * (taskset, executor)
> * (taskset, node)
> In particular, adding (task, node) is critical to making spark fault-tolerant
> of one-bad disk in a cluster, without requiring careful tuning of
> "spark.task.maxFailures". The other additions are also important to avoid
> many misleading task failures and long scheduling delays when there is one
> bad node on a large cluster.
