[jira] [Created] (HBASE-8140) TableMapReduceUtils#addDependencyJar fails when nested inside another MR job

             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.
