Bikas Saha commented on HADOOP-9413:
------------------------------------
bq. Did only a minor update to the patch to note some subtle differences
between setExecutable on Windows and Unix. Check HADOOP-9525 for additional
details. Thanks Chris for the great comment on HDFS-4610 that made me realize
this!
Without a summary of the issue or links to exact explanatory comments in other
jiras, its hard to ascertain what the issue is.
> Introduce common utils for File#setReadable/Writable/Executable and
> File#canRead/Write/Execute that work cross-platform

> 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.
