Subject [jira] [Commented] (CRUNCH-524) Tests leave hbase, test.h2.db files around; pipeline leaves temp crunch-xxx dirs around.
Date Fri, 22 May 2015 10:33:17 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14555952#comment-14555952

Sean Owen commented on CRUNCH-524:
----------------------------------

I think an extra error message is fine. Yes deleteOnExit uses shutdown hooks and yes it will
already be used anyway. It doesn't guarantee cleanup in case of a hard failure, but catches
a lot of cases. You guys may know better than I where in the code these temp dirs could be
explicitly cleaned up too. That's even better, rather than rely on a shutdown hook.

> Minor thing I noticed during running tests: I end up with an {{hbase/}} directory and
{{test.h2.db}} file in my _home directory_. I think the tests can be changed to clean these
up reliably or put them in a better place.
> Also I think we can get the {{/tmp/crunch-xxx}} dirs to be automatically deleted. I see
a lot in my temp dir and this happens on a cluster's temp dir too.
