[jira] [Commented] (SPARK-25692) Flaky test: ChunkFetchIntegrationSuite

    [ https://issues.apache.org/jira/browse/SPARK-25692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16671895#comment-16671895 ] 

Shixiong Zhu commented on SPARK-25692:
--------------------------------------

It's still flaky on Jenkins: [https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-maven-hadoop-2.7/5554/testReport/junit/org.apache.spark.network/ChunkFetchIntegrationSuite/fetchBothChunks/history/]

You may need to run the whole tests together. [https://github.com/apache/spark/pull/22173] added a global thread pool, so other tests may also impact this test suite.

> Looks like the whole test suite is pretty flaky. See: https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-maven-hadoop-2.6/5490/testReport/junit/org.apache.spark.network/ChunkFetchIntegrationSuite/history/
> This may be a regression in 3.0 as this didn't happen in 2.4 branch.
