Hi, I want to write a long running (i.e. never stop it) streaming flink application on a kerberos secured Hadoop/Yarn cluster. My application needs to do things with files on HDFS and HBase tables on that cluster so having the correct kerberos tickets is very important. The stream is to be ingested from Kafka.
One of the things with Kerberos is that the tickets expire after a predetermined time. My knowledge about kerberos is very limited so I hope you guys can help me. My question is actually quite simple: Is there an howto somewhere on how to correctly run a long running flink application with kerberos that includes a solution for the kerberos ticket timeout ? Thanks Niels Basjes
