Apache Spark reassigned SPARK-11326: ------------------------------------ Assignee: (was: Apache Spark) > Split networking in standalone mode > ----------------------------------- > > Key: SPARK-11326 > URL: https://issues.apache.org/jira/browse/SPARK-11326 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Jacek Lewandowski > > Currently, in standalone mode, all components, for all network connections > need to use the same secure token if they want to have any security ensured. > This ticket is intended to split the communication in standalone mode to make > it more like in Yarn mode - application internal communication, scheduler > internal communication and communication between the client and scheduler. > Such refactoring will allow for the scheduler (master, workers) to use a > distinct secret, which will remain unknown for the users. Similarly, it will > allow for better security in applications, because each application will be > able to use a distinct secret as well. > By providing Kerberos based SASL authentication/encryption for connections > between a client (Client or AppClient) and Spark Master, it will be possible > to introduce authentication and automatic generation of digest tokens and > safe sharing them among the application processes. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
