FileContext.mkdir(..) causes a loss of setgid permission of directory created
-----------------------------------------------------------------------------
Key: HADOOP-8130
URL: https://issues.apache.org/jira/browse/HADOOP-8130
Project: Hadoop Common
Issue Type: Bug
Components: fs, util
Affects Versions: 0.23.0
Reporter: Ahmed Radwan
When FileContext.mkdir(..) is used to create a directory inside a parent
directory (which has the setgid permission), the created directory loses the
setgid permission.
We have noticed that in ContainerLocalizer.java:
{code}
private static void initDirs(Configuration conf, String user, String appId,
FileContext lfs, List<Path> localDirs) throws IOException {
.
.
// $x/usercache/$user/appcache/$appId/output
lfs.mkdir(new Path(appBase, OUTPUTDIR), null, false);
.
.
}
{code}
