FAQ
permissions of local files change when using the -file option
-------------------------------------------------------------

Key: HADOOP-3857
URL: https://issues.apache.org/jira/browse/HADOOP-3857
Project: Hadoop Core
Issue Type: Bug
Components: contrib/streaming
Affects Versions: 0.17.1
Environment: Linux
Reporter: S. Alex Smith
Priority: Minor


When running hadoop streaming, all files mentioned in the -file option have their permissions changed from default to 777. If the files are not readable by the owner before hadoop is run the job fails but permissions are still changed (and thus, for example, the job will succeed if run again immediately).
