             Summary: TestFSMainOperationsLocalFileSystem and TestNativeAzureFileSystemOperationsMocked failed when the Hadoop enlistment root path has "x" or "X" in its name
                 Key: HADOOP-9624
                 URL: https://issues.apache.org/jira/browse/HADOOP-9624
             Project: Hadoop Common
          Issue Type: Test
          Components: test
         Environment: Windows
            Reporter: Xi Fang
            Priority: Minor


TestFSMainOperationsLocalFileSystem and TestNativeAzureFileSystemOperationsMocked failed when the Hadoop enlistment root path has "x" or "X" in its name. Here is the the root cause of the failures.

Both classes extend Class FSMainOperationsBaseTest. PathFilter FSMainOperationsBaseTest#TEST_X_FILTER checks if a path has "x" or "X" in its name. Some of the test cases construct a path by combining path "TEST_ROOT_DIR" with a customized partial path. 
The problem is that once the enlistment root path has "x" or "X" in  its name, "TEST_ROOT_DIR" will also has "x" or "X" in its name. The path check will pass even if the customized partial path doesn't have "x" or "X". However, the path filter is supposed to reject this path when the customized partial path doesn't have "x" or "X".

An easy fix is using more complicated char sequence rather than a simple char "x" or "X".
