Eli Collins commented on HADOOP-6988:
-------------------------------------
Being able to specify both MR and HDFS delegation token files upfront when
submitting a job seems reasonable, avoids requiring all clients kinit or use a
tool to merge token files. Env variable philosophy aside (Allen, want to open
a jira with an alternative?) does anyone object to modifying this existing
variable so more than one file can be specified?

> 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.
