LucaCanali opened a new pull request #23518: [SPARK-26600] Update spark-submit usage message
URL: https://github.com/apache/spark/pull/23518
 
 
   ## What changes were proposed in this pull request?
   
   Spark-submit usage message should be put in sync with recent changes in particular regarding K8S support. These are the proposed changes to the usage message:
   
   --executor-cores NUM -> can be useed for Spark on YARN and K8S 
   
   --principal PRINCIPAL  and --keytab KEYTAB -> can be used for Spark on YARN and K8S
   
   --total-executor-cores NUM> can be used for Spark standalone, YARN and K8S 
   
   In addition this PR proposes to remove certain implementation details from the --keytab argument description as the implementation details vary between YARN and K8S, for example.
   
   ## How was this patch tested?
   
   Manually tested
