> Remove unnecessary calls to FileSystem.setOwner() from
> FileOutputCommitterContainer
> -----------------------------------------------------------------------------------
>
> Key: HIVE-17802
> URL: https://issues.apache.org/jira/browse/HIVE-17802
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 2.2.0, 3.0.0
> Reporter: Mithun Radhakrishnan
> Assignee: Chris Drome
> Attachments: HIVE-17802.1.patch, HIVE-17802.2.patch
>
>
> For large Pig/HCat queries that produce a large number of
> partitions/directories/files, we have seen cases where the HDFS NameNode
> groaned under the weight of {{FileSystem.setOwner()}} calls, originating from
> the commit-step. This was the result of the following code in
> FileOutputCommitterContainer:
> {code:java}
> private void applyGroupAndPerms(FileSystem fs, Path dir, FsPermission
> permission,
> List<AclEntry> acls, String group, boolean recursive)
> throws IOException {
> ...
> if (recursive) {
> for (FileStatus fileStatus : fs.listStatus(dir)) {
> if (fileStatus.isDir()) {
> applyGroupAndPerms(fs, fileStatus.getPath(), permission, acls,
> group, true);
> } else {
> fs.setPermission(fileStatus.getPath(), permission);
> chown(fs, fileStatus.getPath(), group);
> }
> }
> }
> }
> private void chown(FileSystem fs, Path file, String group) throws
> IOException {
> try {
> fs.setOwner(file, null, group);
> } catch (AccessControlException ignore) {
> // Some users have wrong table group, ignore it.
> LOG.warn("Failed to change group of partition directories/files: " +
> file, ignore);
> }
> }
> {code}
> One call per file/directory is far too many. We have a patch that reduces the
> namenode pressure.
