> eliminate duplicate FQN tests in different Hadoop modules

> Key: HADOOP-9470
> URL: https://issues.apache.org/jira/browse/HADOOP-9470
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 3.0.0, 2.3.0
> Reporter: Ivan A. Veselovsky
> Assignee: Ivan A. Veselovsky
> Fix For: 3.0.0, 2.3.0
>
> Attachments: find-duplicate-fqns.sh, HADOOP-9470-branch-0.23.patch,
> HADOOP-9470-branch-2--N1.patch, HADOOP-9470-trunk--N1.patch,
> HADOOP-9470-trunk.patch

>
> In different modules of Hadoop project there are tests with identical FQNs
> (fully qualified name).
> For example, test with FQN org.apache.hadoop.util.TestRunJar is contained in
> 2 modules:
>
> ./hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/util/TestRunJar.java
>
> ./hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/test/java/org/apache/hadoop/util/TestRunJar.java
>
> Such situation causes certain problems with test result reporting and other
> code analysis tools (such as Clover, e.g.) because almost all the tools
> identify the tests by their Java FQN.
> So, I suggest to rename all such test classes to avoid duplicate FQNs in
> different modules. I'm attaching simple shell script that can find all such
> problematic test classes. Currently Hadoop trunk has 9 such test classes,
> they are:
> $ ~/bin/find-duplicate-fqns.sh
> # Module
> [./hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/target/test-classes]
> has 7 duplicate FQN tests:
> org.apache.hadoop.ipc.TestSocketFactory
> org.apache.hadoop.mapred.TestFileOutputCommitter
> org.apache.hadoop.mapred.TestJobClient
> org.apache.hadoop.mapred.TestJobConf
> org.apache.hadoop.mapreduce.lib.output.TestFileOutputCommitter
> org.apache.hadoop.util.TestReflectionUtils
> org.apache.hadoop.util.TestRunJar
> # Module
> [./hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-common/target/test-classes]
> has 2 duplicate FQN tests:
> org.apache.hadoop.yarn.TestRecordFactory
> org.apache.hadoop.yarn.TestRPCFactories
