[~hex108], thanks for your contribution. Can we close this jira as duplicated issue of YARN-1979?

> I found it was because testDiskSpaceUtilizationLimit ran before testCreateDirectories when running test, then directory "dirA" was created in test function testDiskSpaceUtilizationLimit. When testCreateDirectories tried to create "dirA" with specified permission, it found "dirA" has already been there and it did nothing.
