> When submit MapReduce job in security mode, we need to collect delegation
> tokens (i.e. delegation token for NameNode, KMS).
> {{addDelegationTokens}} is invoked several times, currently dt for NN is got
> only once if exists. But dt for KMS is got every time, we should fix this.
> Running in real cluster:
