Chuan Liu commented on MAPREDUCE-5349:
--------------------------------------
Thanks Chris for pointing out the JIRA! It is a little strange that the tests
calling {{MiniMRClientClusterFactory}} do not fail on my machine. I think it is
still good to keep branch-2 and trunk in sync on this issue. I will attach a
new patch.

> 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:
> {noformat}
> 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
