TestLocalJobControl test gets OutOfMemoryError on 64-bit Java
-------------------------------------------------------------
Key: HADOOP-3644
URL: https://issues.apache.org/jira/browse/HADOOP-3644
Project: Hadoop Core
Issue Type: Bug
Reporter: Matei Zaharia
Priority: Trivial
Fix For: 0.17.1, 0.18.0, 0.19.0
The TestLocalJobControl unit test fails on 64-bit Java on Linux with an
OutOfMemoryError. Here is the exact Java environment:
$ java -version
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_07-b03, mixed mode)
The test runs fine with 32-bit. The problem is likely that some of the data
structures become bigger when using 32-bit pointers. As a fix, I've suggested
simply increasing the memory available to JUnit.
