Sean Owen created SPARK-1798:
--------------------------------
Summary: Tests should clean up temp files
Key: SPARK-1798
URL: https://issues.apache.org/jira/browse/SPARK-1798
Project: Spark
Issue Type: Bug
Components: Build
Affects Versions: 0.9.1
Reporter: Sean Owen
Priority: Minor
Three issues related to temp files that tests generate -- these should be
touched up for hygiene but are not urgent.
Modules have a log4j.properties which directs the unit-test.log output file to
a directory like [module]/target/unit-test.log. But this ends up creating
[module]/[module]/target/unit-test.log instead of former.
The work/ directory is not deleted by "mvn clean", in the parent and in
modules. Neither is the checkpoint/ directory created under the various
external modules.
Many tests create a temp directory, which is not usually deleted. This can be
largely resolved by calling deleteOnExit() at creation and trying to call
Utils.deleteRecursively consistently to clean up, sometimes in an "@After"
method.
(If anyone seconds the motion, I can create a more significant change that
introduces a new test trait along the lines of LocalSparkContext, which
provides management of temp directories for subclasses to take advantage of.)
