Hi devs, I noticed this test case fails intermittently in Jenkins.
For eg, see the following builds- https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/41991/ https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/41999/ The test failed in different PRs, and the failure looks unrelated to changes in the PRs. Looks like the test was added by the following commit- commit 80e2568b25780a7094199239da8ad6cfb6efc9f7 Author: Imran Rashid <iras...@cloudera.com> Date: Mon Jul 20 10:28:32 2015 -0700 [SPARK-8103][core] DAGScheduler should not submit multiple concurrent attempts for a stag Thanks!
