Subject [jira] [Created] (SPARK-22583) First delegation token renewal time is not 75% of renewal time in Mesos

Kalvin Chau created SPARK-22583:
-----------------------------------

             Summary: First delegation token renewal time is not 75% of renewal time in Mesos
                 Key: SPARK-22583
                 URL: https://issues.apache.org/jira/browse/SPARK-22583
             Project: Spark
          Issue Type: Bug
          Components: Mesos
    Affects Versions: 2.3.0
            Reporter: Kalvin Chau
            Priority: Blocker


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.
