--------------------------------------

             Summary: HADOOP_CLASSPATH is overwritten in MR container
                 Key: MAPREDUCE-6619
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6619
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.8.0, 2.7.2
            Reporter: shanyu zhao
            Assignee: shanyu zhao


Previously env variable HADOOP_CLASSPAH in MR containers inherit from defaults of the worker
node. MAPREDUCE-6454 introduced change to overwrite HADOOP_CLASSPATH completely. This caused
regression. We need to add additional entries to HADOOP_CLASSPATH instead of completely replacing
it.
