--------------------------------
lgtm
Want to just go for 4G rather than 2G or you thinking that if we OOME on 2G,
we'll take a look at the dumped heaps to see what is going on?
Thanks [~ste...@apache.org]
> Hadoop maven surefire-plugin uses must set heap size

> Key: HADOOP-11363
> URL: https://issues.apache.org/jira/browse/HADOOP-11363
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 2.7.0
> Environment: java 8
> Reporter: Steve Loughran
> Assignee: Steve Loughran

>
> Some of the hadoop tests (especially HBase) are running out of memory on Java
> 8, due to there not being enough heap for them
> The heap size of surefire test runs is *not* set in {{MAVEN_OPTS}}, it needs
> to be explicitly set as an argument to the test run.
> I propose
> # {{hadoop-project/pom.xml}} defines the maximum heap size and test timeouts
> for surefire builds as properties
> # modules which run tests use these values for their memory & timeout
> settings.
> # these modules should also set the surefire version they want to use
