Subject [jira] [Commented] (DRILL-4259) Add new functional tests to ensure that failures can be detected independent of the testing environment
Date Tue, 12 Jan 2016 19:45:39 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15094633#comment-15094633

Victoria Markman commented on DRILL-4259:
-----------------------------------------

This would work. If we do it this way, the only difference would be: these "permutations"
are not going to be part of the test suite.

> In DRILL-4243 an out of memory issue was fixed after a change to the memory allocator
made memory limits more strict. While the regression tests had been run by the team at Dremio
prior to merging the patch, running the tests on a cluster with more cores changed the memory
limits on the queries and caused several tests to fail.
> While changes of this magnitude are not going to be common, we should have a test suite
that reliably fails independent of the environment it is run (assuming that there are sufficient
resources for the tests to run).
> It would be good to at least try to reproduce this failure on a few different setups
(cores, nodes in cluster) by adjusting available configuration options and adding tests with
those different configurations so that the tests will fail in different environments.
