------------------------------------
Summary: SparkUI doesn't get killed after test
Key: ZEPPELIN-322
URL: https://issues.apache.org/jira/browse/ZEPPELIN-322
Project: Zeppelin
Issue Type: Bug
Components: build
Affects Versions: 0.5.0
Environment: mvn test environment (with modified listen port for
Zeppelin)
Reporter: Rick Moritz
Priority: Trivial
Running tests may lead to Spark processes not getting killed. This led to 6
Spark instances running "Zeppelin" on my system (so much for reproducability).
I think a potential reason could be failed tests which after an assertion fails
are not properly torn down, or a missing tear down even after successful tests.
I will attempt to narrow it down, but any developer should be able to spot
similar behavior, especially attempting to mvn clean test without an installed
instance of Zeppelin in the local repo (build fails for me at least), or just
regularly testing the full package. It probably won't show up on Travis CI,
since the container gets wiped.
