Subject [jira] [Commented] (HBASE-8607) Run HBase server in an OSGi container
Date Mon, 03 Jun 2013 11:00:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13673005#comment-13673005
] 

Andrew Purtell commented on HBASE-8607:
---------------------------------------

bq. I like the direction you suggest; would proof out two concepts in the one go (osgi and
moving cp hosting out of the regionserver).

[~stack] It would demonstrate if an OSGi runtime can be embedded and if CPs hosted by it can
be unloaded or reloaded, but everything would all still be in the same process.

> Run the HBase server in an OSGi container to support updating custom filters and coprocessor
updates without requiring a region server reboot. Typically, applications that use coprocessors
and custom filters also have shared classes underneath, so putting the burden on the user
to include some kind of version name in the class is not adequate. Including the version name
in the package might work in some cases (at least until dependent jars start to change as
well), but is cumbersome and overburdens the app developer.
