ATTACHMENT ID: 12892929 - PreCommit-HIVE-Build > 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-branch-2.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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
