----------------------------------
Hi Jerry, there is a format problem in my comment yesterday which I did not
noticed.
It should be corrected as :
=====================
1. I tested FileSytem.isDirectory() by a separate program, against the path
with wildcard. It works as expected for the following inputs, for example,
"/user/hbase/\*.jar" or "/user/hbase/coprocessor.\*", isDirectory() returns
false.
=====================
I forgot to add the escape character "\" in front of two "*" in the sentence
above, so the system displays the words between those two "*" into bold.
Sorry if it made you confused.

> 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.
