--------------------------------
Summary: _SUCCESS file should be created with permissions of
parent directory
Key: MAPREDUCE-7221
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7221
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client
Affects Versions: 3.1.2
Reporter: Kevin
The _SUCCESS file is created with the default user permissions ... often
read-only to the current user. This can prevent a second user from
successfully performing operations in the directory that they would otherwise
be able to perform. The permissions of the directory are a much better
representation of the intent of access and the _SUCCESS file's permissions
should not interfere with this intent.
The specific case where I ran into this being a problem: We have an "analytic
pipeline" that can be used by many different users. At the end of the
pipeline, statistics are appended to a Hive table. The _SUCCESS file must
currently be deleted with elevated privileges before the statistics append at
the end of the job.
