----------------------------------
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.
