Mingjie Lai commented on HBASE-3810:
------------------------------------
I had an offline discussion with Gary and Andy, and we agreed to add a new
method -- addCoprocessor() -- to HTableDescriptor which can help ease the
potential difficulty of adding a coprocessor by setting htd attributes.
Since we propose to have htd.addCoprocessor(), it makes sense to have
htd.removeCoprocessor(). In addition, we may want to support adding shell
commands for add/remove coprocessors. But I prefer to address
htd.removeCoprocessor() and shell commands at other jiras.
> Registering a Coprocessor at HTableDescriptor should be less strict

> Project: HBase
> Issue Type: Improvement
> Components: coprocessors
> Affects Versions: 0.92.0
> Environment: all

> Registering a Copressor in the following way will fail as the "Coprocessor$1"
> keyword is case sensitive (instead COPROCESSOR$1 works fine). Removing this
> restriction would improve usability.
> HTableDescriptor desc = new HTableDescriptor(tName);
> desc.setValue("Coprocessor$1",
> path.toString() + ":" + full_class_name +
> ":" + Coprocessor.Priority.USER);
