SQL Client security
Learn about the needed security parameters for Flink SQL Client.
In Kerberos protected environments, you must use
kinit <principal> before
flink-sql-client. The CLI does not support keytab based Kerberos
YARN sessions that
flink-sql-clientis connected to should be started with Kerberos keytab and principal properties:
flink-yarn-session -tm 2096 -s 2 -d -nm "<application_name>" \ -D security.kerberos.login.principal=<username> \ -D security.kerberos.login.keytab=<keytab_name>
