--------------------------------------------------
Summary: Support AM restart in Kerberos secured YARN after the
original token in launch context expires
Key: SAMZA-929
URL: https://issues.apache.org/jira/browse/SAMZA-929
Project: Samza
Issue Type: Sub-task
Reporter: Yi Pan (Data Infrastructure)
In Kerberos secured YARN cluster, an initial token is given in the launch
context to RM for a job. When that token expires, RM will not be able to
restart failed AM. As for now, we will have to re-submit the job to refresh the
token in the launch context.
This ticket is searching for a solution that can refresh the token in the
launch context for AM.
