Hadoop 2.4: java.lang.NoClassDefFoundError: org/apache/hcatalog/mapreduce/InputJobInfo

Question

I have upgraded to a recent Hadoop from Hortonworks:

Hadoop 2.4.0.2.1.2.1-471
Subversion [email protected]:hortonworks/hadoop.git -r 9e5db004df1a751e93aa89b42956c5325f3a4482
Compiled by jenkins on 2014-05-27T18:57Z
Compiled with protoc 2.5.0
From source with checksum 9e788148daa5dd7934eb468e57e037b5
This command was run using /usr/lib/hadoop/hadoop-common-2.4.0.2.1.2.1-471.jar

Before upgrading I wrote a Java MRD program that uses Hive tables both for input & output. In previous version of Hadoop it worked, notwithstanding I got deprecation warnings at compile time for this code:

    Job job = new Job(conf, "Foo");
    HCatInputFormat.setInput(job,InputJobInfo.create(dbName, inputTableName, null));

Now, after updating dependencies to new jars in Hadoop 2.4.0.2.1.2.1-471 and runing the same code I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hcatalog/mapreduce/InputJobInfo

To run my code I use the following settings:

export LIBJARS=/usr/lib/hive-hcatalog/share/hcatalog/hive-hcatalog-core.jar,/usr/lib/hive/lib/hive-exec.jar,/usr/lib/hive/lib/hive-metastore.jar,/usr/lib/hive/lib/libfb303-0.9.0.jar,/usr/lib/hive/lib/jdo-api-3.0.1.jar,/usr/lib/hive/lib/antlr-runtime-3.4.jar,/usr/lib/hive/lib/datanucleus-api-jdo-3.2.6.jar,/usr/lib/hive/lib/datanucleus-core-3.2.10.jar

export HADOOP_CLASSPATH=/usr/lib/hive-hcatalog/share/hcatalog/hive-hcatalog-core.jar,/usr/lib/hive/lib/hive-exec.jar,/usr/lib/hive/lib/hive-metastore.jar,/usr/lib/hive/lib/libfb303-0.9.0.jar,/usr/lib/hive/lib/jdo-api-3.0.1.jar,/usr/lib/hive/lib/antlr-runtime-3.4.jar,/usr/lib/hive/lib/datanucleus-api-jdo-3.2.6.jar,/usr/lib/hive/lib/datanucleus-core-3.2.10.jar

Any ideas why I get java.lang.NoClassDefFoundError: org/apache/hcatalog/mapreduce/InputJobInfo ?

What if you try appending the output of hadoop classpath to your HADOOP_CLASSPATH ? — merours
Does not help. Tried appending it to my HADOOP_CLASSPATH and also used it alone - still the same error. Iteresting thing - my code compiles OK with this new version of Hadoop, but when it runs - can not resolve class! — DarqMoth

I think you should add the following dependency in pom.xml.

<dependency>
     <groupId>org.apache.hcatalog</groupId>
     <artifactId>hcatalog-core</artifactId>
     <version>0.11.0</version>
</dependency>
