Guava Hadoop Classpath Issue

Blogging this because it was slightly too large for a tweet.  If you've got a stacktrace like


java.lang.NoClassDefFoundError: com/google/common/io/LimitInputStream
at org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:467) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1295) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1292) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1642) at org.apache.hadoop.mapreduce.Job.submit(Job.java:1292) at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1313)


You may find this problematic dependency tree
\---org.apache.hadoop:hadoop-client
    +---org.apache.hadoop:hadoop-common
        +---org.apache.hadoop:hadoop-auth

It seems Google has once again broken compatibility in Guava by removing LimitInputStream in Guava 15.  And while much of Hadoop (except the new versions which have upgraded their Guava version) are on an older version of Guva, the hadoop-auth module contains a newer version of Guava that most dependency management tools (aka Maven and Gradle) will choose over the older version.  Adding an exclusion for this transitive dependency should resolve this issue.

IntelliJ and junit-hierarchicalcontextrunner

For those using junit-hierarchicalcontextrunner getting an exception like

java.lang.Exception: The inner class com.mycompany.SomeClassTest$InnerClass is not static.
 at org.junit.runners.BlockJUnit4ClassRunner.validateNoNonStaticInnerClass(BlockJUnit4ClassRunner.java:113)
...

You might be able to get rid of that error (especially if it happens when running in IntelliJ, but not the commandline) by upgrading to JUnit 4.12 and junit-hierarchicalcontextrunner 4.12.0. However, if you're an IntelliJ user, you'll find that running an individual test still runs all the tests. This will be fixed in an upcoming release.

Codehaus Migration

I'll keep this page updated as more information becomes available (let me know if you spot something incorrect or out of date). Also if there's a project not on this list that you think should be, let me know and I'll add it. I know some of these moves are old news, but I listed them anyway since once Codehaus shuts down, any redirects they may have had will stop working.
