> With the shell, when operator wants to remove a table coprocessor, the flow is to
> 1. first use {{decs}} find the the mapping of coprocessor$# e.g. coprocessor$1, where # is the ordered number when the coprocessor was internally added to the table attribute
> 2. issue {{table_att_unset}} with the target `coprocessor$#` that maps to a value that include the unique class name.
> This task is to simplify the flow if the operator know exactly the class name of the added coprocessor, and create a new sub-method to {{alter}}, such that operator can do it only with the class name.
> NOTE that this logic has been added behind the scenes at [TableDescriptorBuilder#removeCoprocessor|https://github.com/apache/hbase/blob/358c4dc9022c507ee0159c1d4916aba41d42cde8/hbase-client/src/main/java/org/apache/hadoop/hbase/client/TableDescriptorBuilder.java#L1537-L1565] for removing `ConstraintProcessor` , and we are just exposing this logic with a new method to {{alter}} command.
