-------------------------------

Vinod, We're probably not on the same wavelength. I agree with all that you 
said about keytabs being the solution for services. But I'm trying to find a 
solution for apps that are started by regular users. There are no keytabs here.

Steve, the let-user-push-new-token solution is possible, although the user 
experience is very bad as it requires periodic intervention. I.e. the user 
can't go on a 2-week vacation.

bq. I guess you are disappointed by the negative feedback here: you had a 
simple solution to the problem of HDFS token expiry without having to 
distribute keytabs.

No, I don't feel emotional about this. I believe that we're all reasonably 
trying to find the right solution for the users. Especially since not everyone 
here understands the use case yet --- There are no keytabs here. These are not 
services.

> Currently the max lifetime of HDFS delegation tokens is hardcoded to 7 days. 
> This is a problem for different users of HDFS such as long running YARN apps. 
> Users should be allowed to optionally specify max lifetime for their tokens.
