Vamsee Yarlagadda created YARN-3835:
---------------------------------------
Summary: hadoop-yarn-server-resourcemanager test package bundles
core-site.xml, yarn-site.xml
Key: YARN-3835
URL: https://issues.apache.org/jira/browse/YARN-3835
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Reporter: Vamsee Yarlagadda
Assignee: Vamsee Yarlagadda
Priority: Minor
It looks like by default yarn is bundling core-site.xml, yarn-site.xml in test
artifact of hadoop-yarn-server-resourcemanager which means that any downstream
project which uses this a dependency can have a problem in picking up the user
supplied/environment supplied core-site.xml, yarn-site.xml
So we should ideally exclude these .xml files from being bundled into the
test-jar. (Similar to YARN-1748)
I also proactively looked at other YARN modules where this might be happening.
{code}
vamsee-MBP:hadoop-yarn-project vamsee$ find . -name "*-site.xml"
./hadoop-yarn/conf/yarn-site.xml
./hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-distributedshell/src/test/resources/yarn-site.xml
./hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-unmanaged-am-launcher/src/test/resources/yarn-site.xml
./hadoop-yarn/hadoop-yarn-client/src/test/resources/core-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/test/resources/core-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/test/resources/core-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/test/resources/yarn-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/target/test-classes/core-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/target/test-classes/yarn-site.xml
./hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-tests/src/test/resources/core-site.xml
{code}
And out of these only two modules (hadoop-yarn-server-resourcemanager,
hadoop-yarn-server-tests) are building test-jars. In future, if we start
building test-jar of other modules, we should exclude these xml files from
being bundled.
