> Update the doc of running MRv1 examples jar on YARN
> ---------------------------------------------------
>
> Key: MAPREDUCE-5459
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5459
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Zhijie Shen
> Assignee: Zhijie Shen
> Attachments: MAPREDUCE-5459.1.patch
>
>
> In addition to adding two env vars: HADOOP_USER_CLASSPATH_FIRST and
> HADOOP_CLASSPATH, we still need to add
> {code}
> <property>
> <name>mapreduce.job.user.classpath.first</name>
> <value>true</value>
> </property>
> {code}
> in mapred-site.xml to make sure that the MRv1 examples jar runs correctly on
> YARN. Some examples will use Java reflection to find the classes in the
> examples jar dynamically when they are running. With this configuration, the
> MRv1 examples jar will appear before the MRv2 examples jar in CLASSPATH of
> the processes in YARN containers. Therefore, the classes found via reflection
> will be picked from MRv1 examples jar instead of MRv2 examples jar as well.
> MapReduce_Compatibility_Hadoop1_Hadoop2.apt.vm needs to be updated to
> document this.
