Ashutosh Chauhan commented on HIVE-2936:
----------------------------------------
I see. Agree on both points. Another point is this increases number on calls on
nn, it will be good to reduce that if possible. How about following:
{code}
boolean success = fs.mkdirs(f);
if(success) {
if (this.inheritPerms && fs.exists(f.getParent())) {
try {
fs.setPermission(f,
fs.getFileStatus(f.getParent()).getPermission());
} catch (IOException ioe) {
LOG.equals("Failed to set permissions");
success = false;
}
}
} else {
return fs.getFileStatus(f).isDir();
}
return success;
{code}
How about this. The case of returning false if you fail to set Permissions is
not clear. I return false, what you think ?
> Warehouse table subdirectories should inherit the group permissions of the

> When the Hive Metastore creates a subdirectory in the Hive warehouse for
> a new table it does so with the default HDFS permissions derived from
> dfs.umask or dfs.umaskmode. There should be a option to inherit the
> permissions of the parent directory (default warehouse or custom database
> directory) so that the table directories have the same permissions as the
> database directories.
