Jonathan Hung created MAPREDUCE-6860:
----------------------------------------
Summary: User intermediate-done-dir permissions should use history
file permissions configuration
Key: MAPREDUCE-6860
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6860
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Jonathan Hung
Currently {{JobHistoryEventHandler}} creates the user intermediate-done-dir
directory here: {noformat} doneDirPrefixPath =
FileContext.getFileContext(conf).makeQualified(new
Path(userDoneDirStr));
mkdir(doneDirFS, doneDirPrefixPath, new FsPermission(
JobHistoryUtils.HISTORY_INTERMEDIATE_USER_DIR_PERMISSIONS));{noformat} which is
hardcoded to 770. But the summary, history, and conf files under this user dir
are configurable via
{{mapreduce.jobhistory.intermediate-done-dir.file.permission}}. So if the
configured permissions has read/write/execute permissions for "other" users,
they will still not have access to these files due to the 770 permission on the
user dir.
I see two options here:
# Reuse {{mapreduce.jobhistory.intermediate-done-dir.file.permission}} as the
permissions for the user dir
# Create a new config for the user dir permissions, using 770 as the default
