Additionally, the user submitting the application automatically receives permission to manage the application, which can optionally be extended to other users. Ensure that you use the hive-site. The Spark driver and executors use the delegation token to connect to the cluster.

For valid authentication, the delegation token must be renewed periodically. For security reasons, the user who is authenticated with the token should not be able to renew it. Therefore, delegation tokens have two associated users: token owner and token renewer. The token renewer is none so that only a DSE internal process can renew it.

When the application is submitted, DSE automatically renews delegation tokens that are associated with Spark application. When the application is unregistered finished , the delegation token renewal is stopped and the token is cancelled. Set Kerberos options, see Defining a Kerberos scheme.

Application memory You can configure additional Java options that are applied by the worker when spawning an executor for the application.

Use the spark. For example: spark. If additional work pools are defined, the default work pool will use the cores available after allocating the cores defined by the work pools. A single executor can borrow more than one core from the worker. The number of cores used by the executor relates to the number of parallel tasks the executor might perform.

The number of cores offered by the cluster is the sum of cores offered by all the workers in the cluster. Application cores In the Spark configuration object of your application, you configure the number of application cores that the application requests from the cluster using either the spark. See the Spark documentation for details about memory and core allocation. DataStax Enterprise can control the memory and cores offered by particular Spark Workers in semi-automatic fashion.
