Dave Marion commented on ACCUMULO-4169:
---------------------------------------
[~bfloss] [~ivan.bella] I'd like to come to some consensus on the "in-use"
issue. You have suggested removing contexts that don't have running scans that
use them in an attempt to reduce the used perm gen space. [~ctubbsii] mentioned
that perm gen space is not as big of an issue with Java 8 (and likely beyond).
So, the question is, I think, is using -XX:+CMSClassUnloadingEnabled in Java 7
sufficient if we remove Contexts that are no longer defined in the
configuration?

> URL: https://issues.apache.org/jira/browse/ACCUMULO-4169
> Project: Accumulo
> Issue Type: Bug
> Components: tserver
> Affects Versions: 1.8.0
> Reporter: Dave Marion
>
> ACCUMULO-3948 added a feature where you could define a context in the
> Accumulo configuration, not set it on a table, and use it in a Scanner.
> However, there is a runnable created n TabletServer.config() that runs every
> 60 seconds that closes context that are not defined on a table. Suggesting
> that we have the context cleaner not close any context defined in the
> configuration.
