Using Hadoop version 0.20.. I am creating a chain of jobs job1 and job2 (mappers of which are in x.jar, there is no reducer) , with dependency and submitting to hadoop cluster using JobControl. Note I have setJarByClass and getJar gives the correct jar file, when checked before submission.
Submission goes through and there seem to be no errors in user logs and jobtracker. But I dont see my Mapper getting executed (no sysouts or log output), but default output seems to be coming to the output folder (input file is read as is and output). I am able to run the job directly using x.jar, but I am really out of clues as to why it is not running with Jobcontrol. -- View this message in context: http://old.nabble.com/The-Mapper-does-not-run-from-JobControl-tp33276756p33276756.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
