Hi, I seem to be having a problem with the job cache on the JobTracker of my (single-node, DataNode, NameNode, JobTracker, TaskTracker all on same machine) Hadoop cluster. I've been recompiling my code multiple times, and the class files in my jarfile are correct (unzipped, checked for new string constants added in println's to check that the new version was correctly compiled), but the class files in the mapred.local directory in the taskTracker/jobcache/<job id>/jars directory are the ones from the old version.
Has anyone encountered a similar problem where your newly compiled code just refuses to run and every time you submit the new jar file some older version ends up getting executed? Thanks, Jiaqi
