S3 File Permissions
-------------------
Key: MAPREDUCE-1736
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1736
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.22.0
Environment: Hadoop cluster using 3 small Amazon EC2 machines and the
S3FileSystem.
Hadoop compiled from latest trunc: 0.22.0-SNAPSHOT
core-site:
fs.default.name=s3://my-s3-bucket
fs.s3.awsAccessKeyId=[key id omitted]
fs.s3.awsSecretAccessKey=[secret key omitted]
hadoop.tmp.dir=/mnt/hadoop.tmp.dir
hdfs-site: empty
mapred-site:
mapred.job.tracker=[domU-XX-XX-XX-XX-XX-XX.compute-1.internal:9001]
mapred.map.tasks=6
mapred.reduce.tasks=6
Reporter: Danny Leshem
Priority: Blocker
Fix For: 0.22.0
Till lately I've been using 0.20.2 and everything was ok. Now I'm using the
latest trunc 0.22.0-SNAPSHOT and getting the following thrown:
Exception in thread "main" java.io.IOException: The ownership/permissions on
the staging directory
s3://my-s3-bucket/mnt/hadoop.tmp.dir/mapred/staging/root/.staging is not as
expected. It is owned by and permissions are rwxrwxrwx. The directory must be
owned by the submitter root or by root and permissions must be rwx------

(The "it is owned by ... and permissions " is not a mistake, seems like the
empty string is printed there)
