------------------------------------
When running in CDH4 branch(which is using MR2 cluster), in a real non-secure
cluster, always getting the following exception:
Exception in thread "Thread-31" java.lang.RuntimeException: Error while reading

After working a patch, using HostUtil.getTaskLogUrl() to retrieve the log, the
same exception still happens.
Found out that, for this intentionally failed testcase, no log generated at all.
