> Resort to Java process API in test suites forking subprocesses
> --------------------------------------------------------------
>
> Key: SPARK-9939
> URL: https://issues.apache.org/jira/browse/SPARK-9939
> Project: Spark
> Issue Type: Test
> Components: SQL
> Affects Versions: 1.5.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
> Priority: Critical
>
> The following SQL test suites fork subprocesses and have been flaky for quite
> a while and fail now and then due to mysterious timeouts:
> - {{CliSuite}}
> - {{HiveThriftBinaryServerSuite}}
> - {{HiveSparkSubmitSuite}}
> - {{HiveThriftHttpServerSuite}}
> One of the possible reasons of this is a known bug of Scala process API
> ([SI-8768|https://issues.scala-lang.org/browse/SI-8768]). Resorting to Java
> process API may possibly fix these flaky tests.
