[jira] [Commented] (MAHOUT-1356) Ensure unit tests fail fast when writing outside mvn target directory

["Dawid Weiss (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-1356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836066#comment-13836066 ] 

Dawid Weiss commented on MAHOUT-1356:
-------------------------------------

Suneel you may want to check out how Apache Lucene/ Solr runs randomized tests in multiple concurrent JVMs -- the "allowed" writing space is configured (and enforced) using a security manager. There is some trickery involved because the runner itself must be allowed to write to certain locations, but it's definitely a good source to copy/ paste from.
