> Allow to disable automatic shipping of dependency jars for mapreduce jobs

> Key: HBASE-3076
> URL: https://issues.apache.org/jira/browse/HBASE-3076
> Project: HBase
> Issue Type: Improvement
> Components: mapreduce
> Reporter: Bruno Dumon

> Since HBASE-3001, TableMapReduceUtil.initTableMap/ReduceJob will
> automatically upload the HBase jars needed to execute a map reduce job.
> In my case I am building a job jar using Maven's assembly plugin, this way
> all the necessary dependencies are in the job jar. So in such case the
> default behavior of HBase causes some needless upload work. It also uploads
> hadoop-core itself which is not necessary.
> Therefore I propose to add a variant of the initTableMap/ReduceJob methods
> with an extra boolean argument to disable the automatic adding of dependency
> jars.
> I will attach a patch with the proposed change.
> Note that everything works as is, this is just an optimization.
