Subject [jira] [Commented] (ACCUMULO-2774) Update pom to ensure enough memory for tests
Date Tue, 06 May 2014 18:59:15 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13990996#comment-13990996
] 

Jessica Seastrom commented on ACCUMULO-2774:
--------------------------------------------

Java opts set via MAVEN_OPTS are not passed to the surefire-plugin when tests execute. The
heap size for the surefire-plugin can be set in the pom.xml file using:
<configuration>
 <argLine>-Xmx<some_value></argLine>
</configuration>

-Xmx768 works. (Via testing the acceptable value seems to be 512 < Xmx <= 768.

At least one occurence was on MacOS where Java was Apple Java 1.6. Another way to solve this
issue is to set JAVA_HOME to a JAVA version with a larger config heapsize, but this patch
ensures that the heap size is adequate for the test regardless of these low level details.

> 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.
