Subject [jira] [Commented] (ACCUMULO-708) Modify ClassLoader to support different applications / multi-tenancy
Date Mon, 29 Oct 2012 18:14:12 GMT


Josh Elser commented on ACCUMULO-708:

bq. I used /accumulo/classpath as an example, it made sense to me

Cool, I'm making the assumption that this will be useful to a large number of people, and
thus thinking forward to how users would want to use this. Using `instance.dfs.dir`/{classpath,lib,whatever}
would allow multiple separate instances to be run over the same HDFS instance which could
be very useful. That should also "guarantee" you a unique HDFS directory.

application contexts. I'll be modifying the ticket as the idea matures.
