> Currently you can specify the location of the coprocessor jar in the table coprocessor
attribute.
> The problem is that it only allows you to specify one jar that implements the coprocessor.
 You will need to either bundle all the dependencies into this jar, or you will need to copy
the dependencies into HBase lib dir.
> The first option may not be ideal sometimes.  The second choice can be troublesome too,
particularly when the hbase region sever node and dirs are dynamically added/created.
> There are a couple things we can expand here.  We can allow the coprocessor attribute
to specify a directory location, probably on hdfs.
> We may even allow some wildcard in there.
