Subject [jira] [Commented] (ACCUMULO-868) Explore configuring vfs cache
Date Thu, 22 Nov 2012 02:46:58 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13502555#comment-13502555
] 

Dave Marion commented on ACCUMULO-868:
--------------------------------------

The current implementation uses the SoftRefFilesCache and the ON_RESOLVE cache strategy. See
[1] for a list of VFS cache types. See [2] for the different cache strategies. We may also
want to add the class unloading JVM options referenced in ACCUMULO-599.

> The current caching of jars is in /tmp and seems to be per process.   Can this be made
to survive process restarts?  Similar to rsync.
