[jira] [Resolved] (MAPREDUCE-5011) While Running Word Count in
Hadoop showing following errors
[ https://issues.apache.org/jira/browse/MAPREDUCE-5011?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karthik Kambatla resolved MAPREDUCE-5011.
-----------------------------------------
Resolution: Invalid
The command is missing the _class to run_ immediately after the jar, assumes the input argument is the class and fails to find that class.
