Gary Helmling commented on HBASE-3810:
--------------------------------------
In addition to relaxing the matching on the table attribute name for
coprocessor entries, we should relax the parsing of the attribute values
defining the coprocessor classes:
* fix regex to account for whitespace around ":" separators
* make path portion optional -- we already skip the path handling if the class
can be loaded by the classloader
* make priority optional and default to "USER"
This should make table attribute based configuration a bit more friendly.
> Registering a Coprocessor at HTableDescriptor should not be case sensitive

> Project: HBase
> Issue Type: Improvement

> Affects Versions: 0.92.0
> Environment: all
> Reporter: Joerg Schad
> Priority: Minor

> 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);
