----------------------------------
Hi Jerry, thanks for your comments!
1. Yes, it still works if user specifies a jar. I verified it using HBase 1.2.0
2. If a directory is specified, all jar(*.jar) directly in the directory are
included. But the code will not search files in the subtree rooted in the
directory, i.e. the sub-directories of the directory specified. I high-lights
that in the doc
3. Yes, support wildcard at the end level of the path string, such as
"/user/hbase/\*.jar" or "/user/hbase/coprocessor\*.jar"
> Expand how table coprocessor jar and dependency path can be specified

> 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.
