-----------------------------------

             Summary: TableMapReduceUtils#addDependencyJar fails when nested inside another
MR job
                 Key: HBASE-8140
                 URL: https://issues.apache.org/jira/browse/HBASE-8140
             Project: HBase
          Issue Type: Bug
          Components: mapreduce
            Reporter: Nick Dimiduk
            Assignee: Nick Dimiduk


TableMapReduceUtils#addDependencyJar is used when configuring a mapreduce job to make sure
dependencies of the job are shipped to the cluster. The code depends on finding an actual
jar file containing the necessary classes. This is not always the case, for instance, when
run at the end of another mapreduce job. In that case, dependency jars have already been shipped
to the cluster and expanded in the parent job's run folder. Those dependencies are there,
just not available as jars.
