I couldnt quite figure out where in the dependency tree this was getting pulled in from but generally is a good idea to exclude all tests.jar files from the lib.

This llap-common-tests that you see in the lib is most probably because of missing <scope>tests<scope> here

hive/llap-server/pom.xml

Lines 330 to 335 in ee6848d

	<dependency>
	<groupId>org.apache.hive</groupId>
	<artifactId>hive-llap-common</artifactId>
	<version>${project.version}</version>
	<classifier>tests</classifier>
	</dependency>

By default it is taking compile scope and getting packaged. Would be good to correct there as well
