Thanks for taking a look!
The exception is not after 24 hours, but after the token renewal interval
configured in hdfs-site (I set it to like 10 mins). I didn't try kinit-ing
before. I can give that a shot.
I am going to make some change such that it works for both yarn client and
cluster mode without too much un-clean code changes.
