Add support for reading multiple hadoop delegation token files
--------------------------------------------------------------
Key: HADOOP-6988
URL: https://issues.apache.org/jira/browse/HADOOP-6988
Project: Hadoop Common
Issue Type: Improvement
Components: security
Affects Versions: 0.22.0
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
It would be nice if there were a way to specify multiple delegation token files
via the HADOOP_TOKEN_FILE_LOCATION environment variable and the
"mapreduce.job.credentials.binary" configuration value. I suggest a
colon-separated list of paths, each of which is read as a separate delegation
token file.
