Description

Test added with the support for "NetworkTopology with NodeGroup" fails on Windows.

Relevant section from the test log:

2012-12-24 23:51:01,835 WARN datanode.DataNode (DataNode.java:makeInstance(1582)) - Invalid directory in dfs.data.dir: Incorrect permission for I:/git/project/hadoop-monarch/build/test/data/dfs/data/data1, expected: rwxr-xr-x, while actual: rwx------
2012-12-24 23:51:01,911 WARN datanode.DataNode (DataNode.java:makeInstance(1582)) - Invalid directory in dfs.data.dir: Incorrect permission for I:/git/project/hadoop-monarch/build/test/data/dfs/data/data2, expected: rwxr-xr-x, while actual: rwx------
2012-12-24 23:51:01,911 ERROR datanode.DataNode (DataNode.java:makeInstance(1588)) - All directories in dfs.data.dir are invalid.

Default permissions on Windows are 700 while datanode expects 755.

We already fixed this in MiniDFSCluster in branch-1-win. A similar fix is needed in MiniDFSClusterWithNodeGroup.
