             Summary: Introduce common utils for File#setReadable/Writable/Executable and File#canRead/Write/Execute that work cross-platform
                 Key: HADOOP-9413
                 URL: https://issues.apache.org/jira/browse/HADOOP-9413
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Ivan Mitic
            Assignee: Ivan Mitic
             Fix For: 3.0.0


So far, we've seen many unittest and product bugs in Hadoop on Windows because Java's APIs that manipulate with permissions do not work as expected. We've addressed many of these problems on one-by-one basis (by either changing code a bit or disabling the test). While debugging the remaining unittest failures we continue to run into the same patterns of problems, and instead of addressing them one-by-one, I propose that we expose a set of equivalent wrapper APIs that will work well for all platforms.

Scanning thru the codebase, this will actually be a simple change as there are very few places that use File#setReadable/Writable/Executable and File#canRead/Write/Execute (5 files in Common, 9 files in HDFS).

HADOOP-8973 contains additional context on the problem.
