------------------------------------
Summary: TestClusterMapReduceTestCase and TestJobName fail on
Windows in branch-2
Key: MAPREDUCE-5349
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5349
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.1.0-beta
Reporter: Chuan Liu
Assignee: Chuan Liu
Priority: Minor
The two unit tests fails due to MiniMRCluster use test class fullname in
branch-2, instead of simple name as in trunk, to construct the MiniMRCluster
identifier. Full name in the identifier almost always leads to a command script
path with length larger than 260 characters which will generate an exception
{{DefaultContainerExecutor.launchContainer()}} when launching the container
script.
The exception looks like the follows:

2013-06-24 09:45:03,060 WARN [ContainersLauncher #0] launcher.ContainerLaunch
(ContainerLaunch.java:call(262)) - Failed to launch container.
java.io.IOException: Cannot launch container using script at path

because it exceeds the maximum supported path length of 260 characters.
Consider configuring shorter directories in yarn.nodemanager.local-dirs.
