[jira] [Created] (HBASE-16700) Allow for coprocessor whitelisting

Clay B. created HBASE-16700:
-------------------------------

             Summary: Allow for coprocessor whitelisting
                 Key: HBASE-16700
                 URL: https://issues.apache.org/jira/browse/HBASE-16700
             Project: HBase
          Issue Type: Improvement
          Components: Coprocessors
            Reporter: Clay B.
            Priority: Minor


Today one can turn off all non-system coprocessors with {{hbase.coprocessor.user.enabled}} however, this disables very useful things like Apache Phoenix's coprocessors. Some tenants of a multi-user HBase may also need to run bespoke coprocessors. But as an operator I would not want wanton coprocessor usage. Ideally, one could do one of two things:
* Allow coprocessors defined in {{hbase-site.xml}} -- this can only be administratively changed in most cases
* Allow coprocessors from table descriptors but only if the coprocessor is whitelisted
