Description

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.
