> The first renewal time of the delegation tokens is the exact renewal time. This could
lead to a situation where the tokens don't make it to executors in time, and the executors
will be working with expired tokens (and Exception out).
> The subsequent renewal times are correctly set to 75% of total renewal time. The initial
renewal time just needs to be set to 75% of the renewal time.
