Subject [jira] [Commented] (ACCUMULO-4169) TabletServer.config contextCleaner removes contexts that are not set on a table
Date Thu, 24 Mar 2016 18:19:25 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15210700#comment-15210700

Christopher Tubbs commented on ACCUMULO-4169:
---------------------------------------------

bq. The concern I have is that each class loader takes up perm-gen space. So cleaning them
out if not being used seems prudent.

Not that it matters much, but that's less of an issue running on JRE8, which is the only JRE
still receiving public updates, because JRE8 does away with the separate PermGen space. My
personal recommendation is that users should really only be running on a current JRE which
is still receiving updates, if at all possible.

> 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.
