[jira] [Created] (HADOOP-12261) Surefire needs to make sure the JVMs it fires up are 64-bit

Alan Burlison created HADOOP-12261:
--------------------------------------

             Summary: Surefire needs to make sure the JVMs it fires up are 64-bit
                 Key: HADOOP-12261
                 URL: https://issues.apache.org/jira/browse/HADOOP-12261
             Project: Hadoop Common
          Issue Type: Bug
          Components: test
    Affects Versions: 2.7.1
            Reporter: Alan Burlison


hadoop-project/pom.xml sets maven-surefire-plugin.argLine to include -Xmx4096m. Allocating  that amount of memory requires a 64-bit JVM, but on platforms with both 32 and 64-bit JVMs surefire runs the 32 bit version by default and tests fail to start as a result. "-d64" should be added to the command-line arguments to ensure a 64-bit JVM is always used.
