[EMAIL PROTECTED] commented on HADOOP-31: ----------------------------------------- That will work. Thanks. (I'd close this issue but I don't have sufficent permissions). > Stipulate main class in a job jar when using 'hadoop jar JARNAME' > ----------------------------------------------------------------- > > Key: HADOOP-31 > URL: http://issues.apache.org/jira/browse/HADOOP-31 > Project: Hadoop > Type: New Feature > Reporter: [EMAIL PROTECTED] > Priority: Minor > > One use case I forsee is building one jar but using this one jar running > multiple jobs: E.g. A single nutch job jar would now be used to do indexing > job, later same jar is used to do dedup, etc. Currently, the recently added > hadoop 'jar' option just takes the jar name then looks in the jar MANIFEST.MF > for the Main-Class, failing if not present. This is grand but for the > scenario above, it means I have to create a jar per job I want to run -- each > with a different MANIFEST.MF#Main-Class entry. > Can we pass the Main-Class on the hadoop command-line as an (optional) > argument to 'hadoop jar JAR_NAME'?
