Description

JUnit jar path is different each hadoop version.

$ find hadoop-2.9.2 -name "junit*.jar"
hadoop-2.9.2/share/hadoop/common/lib/junit-4.11.jar
hadoop-2.9.2/share/hadoop/mapreduce/lib/junit-4.11.jar
$ find hadoop-3.0.0 -name "junit*.jar"
hadoop-3.0.0/share/hadoop/common/lib/junit-4.11.jar
$ find hadoop-3.1.3 -name "junit*.jar"
hadoop-3.1.3/share/hadoop/mapreduce/lib/junit-4.11.jar
$ find hadoop-3.2.1 -name "junit*.jar"
hadoop-3.2.1/share/hadoop/mapreduce/lib/junit-4.11.jar
$ find hadoop-3.3.0-SNAPSHOT -name "junit*.jar"
hadoop-3.3.0-SNAPSHOT/share/hadoop/tools/lib/junit-4.12.jar

Since create-slim-hadoop-tar.sh removes the tools directory, the junit jar is removed after hadoop-3.1 that is necessary for Dyno-DNs.
