Szehon Ho reassigned HIVE-6648:
-------------------------------
Assignee: Szehon Ho
> Permissions are not inherited correctly when tables have multiple partition
> columns
> -----------------------------------------------------------------------------------
>
> Key: HIVE-6648
> URL: https://issues.apache.org/jira/browse/HIVE-6648
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Henry Robinson
> Assignee: Szehon Ho
>
> {{Warehouse.mkdirs()}} always looks at the immediate parent of the path that
> it creates when determining what permissions to inherit. However, it may have
> created that parent directory as well, in which case it will have the default
> permissions and will not have inherited them.
> This is a problem when performing an {{INSERT}} into a table with more than
> one partition column. E.g., in an empty table:
> {{INSERT INTO TABLE tbl PARTITION(p1=1, p2=2) ... }}
> A new subdirectory /p1=1/p2=2 will be created, and with permission
> inheritance (per HIVE-2504) enabled, the intention is presumably for both new
> directories to inherit the root table dir's permissions. However,
> {{mkdirs()}} will only set the permission of the leaf directory (i.e.
> /p2=2/), and then only to the permissions of /p1=1/, which was just created.
> {code}
> public boolean mkdirs(Path f) throws MetaException {
> FileSystem fs = null;
> try {
> fs = getFs(f);
> LOG.debug("Creating directory if it doesn't exist: " + f);
> //Check if the directory already exists. We want to change the
> permission
> //to that of the parent directory only for newly created directories.
> if (this.inheritPerms) {
> try {
> return fs.getFileStatus(f).isDir();
> } catch (FileNotFoundException ignore) {
> }
> }
> boolean success = fs.mkdirs(f);
> if (this.inheritPerms && success) {
> // Set the permission of parent directory.
> // HNR: This is the bug - getParent() may refer to a just-created
> directory.
> fs.setPermission(f, fs.getFileStatus(f.getParent()).getPermission());
> }
> return success;
> } catch (IOException e) {
> closeFs(fs);
> MetaStoreUtils.logAndThrowMetaException(e);
> }
> return false;
> }
> {code}
