Subject [jira] [Commented] (ACCUMULO-708) Modify ClassLoader to support different applications / multi-tenancy
Date Tue, 07 Aug 2012 12:29:07 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13430312#comment-13430312

Marc Parisi said:

I think we should have a scan time class loader context that enables fully
hot swappable analysis and iteration. Security would need to be enforced,
but if we did that we could simply set the jar ala hadoop map/reduce and
have an iterator hot loaded in a different way for a different scan
session.

> I'd like to expand the current classloader to support loading classes from HDFS and different
application contexts. I'll be modifying the ticket as the idea matures.
