Subject [jira] [Commented] (YARN-1562) Getting ClassNotFoundException even though jar is included in lib folder
Date Mon, 06 Jan 2014 06:33:55 GMT

    [ https://issues.apache.org/jira/browse/YARN-1562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13862801#comment-13862801

Rohith commented on YARN-1562:
------------------------------

For Yarn Application, classpath is considered from "yarn.application.classpath". Try to set
this property and rerun the program.
