checkPath() throws IllegalArgumentException
-------------------------------------------

                 Key: HADOOP-1373
                 URL: https://issues.apache.org/jira/browse/HADOOP-1373
             Project: Hadoop
          Issue Type: Bug
    Affects Versions: 0.12.3
         Environment: Windows, Linux
            Reporter: Konstantin Shvachko
             Fix For: 0.13.0


This was introduced recently in one of the patches committed around 05/15 or 05/14.
I am running TestDFSIO on a two node cluster. Here is the exception I get

07/05/15 19:14:53 INFO mapred.TaskInProgress: Error from task_0001_m_000007_0: java.lang.IllegalArgumentException:
Wrong FS: hdfs://MY-HOST:7017/benchmarks/TestDFSIO/io_control/in_file_test_io_7, expected:

I confess, my config on one of the machines specifies name-node "MY-HOST:7017" and on the
other one "my-host:7017".
But that was acceptable before and should stay that way in the future afaiu.
