Subject [jira] [Commented] (ACCUMULO-4169) TabletServer.config contextCleaner removes contexts that are not set on a table
Date Wed, 23 Mar 2016 15:42:25 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15208616#comment-15208616
] 

Brian Loss commented on ACCUMULO-4169:
--------------------------------------

I like Ivan's idea. Configurable time window to clean up if the context is unused w/in the
window. If the time were set to a negative number, it could be treated as "infinite" time
in which case it would only clean up the context when it is no longer defined. This approach
would still allow the scenario specified in the ticket description.

> 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.
