Dave Beech commented on MRUNIT-159:
-----------------------------------
Hi Jakub - thanks for reporting this. I've replaced the use of the missing
addLocalFiles and addLocalArchives methods with our own helper methods which
set the cache config parameters directly. Can you test this and let me know if
it solves your issue?
> MRUnit not compiling with hadoop 0.23.3
> ---------------------------------------

> Key: MRUNIT-159
> URL: https://issues.apache.org/jira/browse/MRUNIT-159
> Project: MRUnit
> Issue Type: Bug
> Affects Versions: 1.0.0
> Reporter: Jakub
> Assignee: Dave Beech
> Priority: Critical
>
> I tried to write test using mrunit 1.0.0 ( i need to init cache, which is
> unavaliable in already relased versions)
> when I run my code I get:
> java.lang.IncompatibleClassChangeError: Found interface
> org.apache.hadoop.mapreduce.TaskInputOutputContext, but class was expected
> at
> org.apache.hadoop.mrunit.internal.mapreduce.AbstractMockContextWrapper.createCommon(AbstractMockContextWrapper.java:53)
> I read other issues like https://issues.apache.org/jira/browse/MRUNIT-56 and
> decided to recompile mrunit.
> I've downloaded source, and then:
> mvn install -DskipTests
> Build succes
> mvn install -DskipTests -Dhadoop.version=2
> Build success
> tried both output version with my code:
> mrunit-1.0.0-SNAPSHOT-hadoop1.jar
> mrunit-1.0.0-SNAPSHOT-hadoop2.jar
> but was still getting exception
> I've changed pom.xml specificHadoopVersion to:
> <specificHadoopVersion>0.23.3</specificHadoopVersion>
> and then:
> mvn clean
> mvn install -DskipTests -Dhadoop.version=2
> and there are compilation errors:
> [ERROR] COMPILATION ERROR :
> [INFO] -------------------------------------------------------------
> [ERROR]
> /home/kuba/studia/magisterka/mrunit/src/main/java/org/apache/hadoop/mrunit/TestDriver.java:[464,24]
> error: cannot find symbol
> [ERROR] class DistributedCache
> /home/kuba/studia/magisterka/mrunit/src/main/java/org/apache/hadoop/mrunit/TestDriver.java:[478,24]
> error: cannot find symbol
> [INFO] 2 errors
> that's because initDistributedCache method uses
> DistributedCache.addLocalFiles(), which is unavaliable in Hadoop 0.23.3
> I tried to fix it, but I'm new to hadoop ant havent succeed yet, any help,
> please?
