Abstract: Secured data access in virtual data processing is described. An example includes instructions to receive a request from an application in a compute node of a compute cluster in a virtual data processing environment to access a secured data source for a user, the virtual data processing environment including a multiple secured data sources that are accessible by compute nodes of the virtual compute cluster; fetch a credential in a current application context and forward the credential for validation; validate the credential with a credential authority; and, upon successfully validating the credential, authenticate the user at the secured data source and establish a connection with the secured data source.

Abstract: Described herein are systems, methods, and software to enhance the allocation of cache resources to virtual nodes. In one implementation, a configuration system in large-scale processing environment is configured to identify a request to initiate a large-scale processing framework (LSPF) cluster, wherein the LSPF cluster comprises a plurality of virtual nodes, and identify host computing resources of a host computing system allocated to each virtual node of the LSPF cluster. The configuration system further allocates cache memory of a cache service to each of the virtual nodes based on the host computing resources, and initiate the LSPF cluster in the computing environment.
