Subject [jira] [Commented] (ACCUMULO-2774) Update pom to ensure enough memory for tests
Date Tue, 06 May 2014 19:54:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13991051#comment-13991051

Bill Havanki commented on ACCUMULO-2774:
----------------------------------------

We found that we only needed to increase the maximum heap size, which is configured with -Xmx.
With that, and even without setting -Xms for the initial heap size, the test could succeed
on the affected platforms.

(I also tried on my system, which wasn't affected by default. If I specifically configured
-Xmx to 512m, I could stimulate the failure, but not for 768m.)

> On some systems JRE defaults don't provide enough heap to deal with all of our tests.
Namely, org.apache.accumulo.core.security.crypto.BlockedIOStreamTest requires a fair bit of
space (in the 768MB - 1GB range).
> The amount provided by default varies by JRE and by system specs. Our pom should ensure
that by default our tests ask for as much as they'll need.
