Karthik Kambatla commented on YARN-1429:
----------------------------------------
Wonder if we should add YARN_CLASSPATH to CLASSPATH before adding the jars
under YARN_DIR and YAR_LIB_JARS_DIR:
{code}
CLASSPATH=${CLASSPATH}:$HADOOP_YARN_HOME/${YARN_DIR}/*
CLASSPATH=${CLASSPATH}:$HADOOP_YARN_HOME/${YARN_LIB_JARS_DIR}/*
+# Add user defined YARN_CLASSPATH to the class path (if defined)
+if [ -n "$YARN_CLASSPATH" ]; then
+ CLASSPATH=${CLASSPATH}:${YARN_CLASSPATH}
+fi
+
{code}
> YARN_CLASSPATH is referenced in yarn command comments but doesn't do anything
