Lars Hofhansl commented on HBASE-6527:
--------------------------------------
For Coproc the regions have to reloaded (i.e. the table disabled and enabled
again).
Coproc can be loaded in three way:
# as part of the system classpath. In which case they need to be deployed to
each machine and HBase needs to be bounced.
# as local jar outside of the system classpath. In this case the jar needs to
be deployed to each machine, and only the regions need to be bounced
(disable/enable).
# via a jar uploaded to HDFS , in this case the regions need to be bounced
(disable/enable)
It's 100% dynamic as we have at least a disable/enable cycle. But it's better
than what we have with Filters now. I seem to recall that there was a jira for
this somewhere. It's not an entirely trivial task.
