Subject [jira] [Commented] (YARN-105) DEFAULT_YARN_APPLICATION_CLASSPATH is incomplete
Date Thu, 13 Sep 2012 13:42:07 GMT

    [ https://issues.apache.org/jira/browse/YARN-105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454890#comment-13454890
] 

Robert Joseph Evans commented on YARN-105:
------------------------------------------

Also YARN is not supposed to have any knowledge of map reduce.  We should not launch map reduce
applications with the yarn command.  There is the mapred command for that.

> Currently, DEFAULT_YARN_APPLICATION_CLASSPATH only includes following:
> "$HADOOP_CONF_DIR", "$HADOOP_COMMON_HOME/share/hadoop/common/*",
> "$HADOOP_COMMON_HOME/share/hadoop/common/lib/*",
> "$HADOOP_HDFS_HOME/share/hadoop/hdfs/*",
> "$HADOOP_HDFS_HOME/share/hadoop/hdfs/lib/*",
> "$YARN_HOME/share/hadoop/yarn/*",
> "$YARN_HOME/share/hadoop/yarn/lib/*"
> However, $HADOOP_MAPRED_HOME/share/hadoop/mapreduce/* and $HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*
are missing. All classes of mapreduce projects can't be found.
