      Description

      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.
