Weberte updated HADOOP-9413:
----------------------------
Description:
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.
> Introduce common utils for File#setReadable/Writable/Executable and
> File#canRead/Write/Execute that work cross-platform
