------------------------------------
Summary: 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.
