Clay B. commented on HBASE-16700:
---------------------------------
[~stack] Thanks for thinking of the release notes! I can't seem to do a better
job than what you have. The best I came up with was:
"This features allows restricting filesystem deployed user coprocessors (those
defined against a table with a JAR path). Allows for classpath coprocessors
(e.g. Apache Phoenix) and coprocessors deployed from whitelisted file-system
paths."
Otherwise, I would think these should be medium tests based on being nine tests
(each are certainly expected to take less than 50 seconds) so that'd be a max
of less than 10 minutes total serially (though they can be parallelized). As I
understand a medium test it should take less than 30 minutes; but it may be
true that there's not a need for all developers to end up running this?
Unfortunately, the Jenkins link seems to have become a 404, so I can't see
which test(s) timed out to understand how they may have hung up?

> 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
