The steps are given in the apache mapred tutorial. However, I will restate them for your case:
First of all compile your AB.java file and then put all the classes generated into a single jar file using jar -cvf p.jar AB.class [other class files if any] If your AB.java is in a package then run javac -cp [path to hadoop jar file] -d jodDirectory AB.java jar -cvf p.jar -C jobDirectory/ . Now you can run your hadoop job using: hadoop jar p.jar path.to.AB.class.file.in.the.jar.file [args] --Akhil jdh wrote: > > Hi, everyone~ > I have a question about bin/hadoop jar.

For example, when I used command like this " bin/hadoop jar > p.jar AB", it could not run until I placed the AB class in my hadoop dir. > Can somebody help me about how to use hadoop jar? > Thanks! > -- View this message in context: http://www.nabble.com/Can-you-help-me-about-how-to-use-hadoop-jar--tp24427337p24432699.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
