Any value less than or equal to zero will be considered as disabled.Д¬.-application-lifetimeДefault lifetime of an application which is submitted to a queue in seconds. Maximum lifetime of an application which is submitted to a queue in seconds. State of queue can be one of Running or Stopped.Д¬.-application-lifetime Setting this value to -1 sets maximum capacity to 100%.Д¬. Maximum queue capacity in percentage (%) as a float OR as absolute resource queue maximum capacity. The multiple of the queue capacity which can be configured to allow a single user to acquire more resources.Д¬.-capacity executor.classД¬ontainer executors for a specific operating system(s). Maximum percent of resources in the cluster that can be used to run application masters. The number of pool users for the linux container executor in secure mode. The maximum allocation for every container request at the resource manager, in terms of virtual CPU cores. Number of CPU cores that can be allocated for containers. The maximum allocation for every container request at the resource manager. memory-mbДЄmount of physical memory, in MB, that can be allocated for containers.

The number of cores to use on each executor.ДЄmount of memory to use for the driver process. The number of executors for static allocation.

The amount of off-heap memory to be allocated per driver in cluster mode. Number of cores to use for the driver process, only in cluster mode. Queue capacity in percentage (%) as absolute resource queue minimum capacity for root queue. The capacity scheduler with predefined queue called root.Д¬. The ResourceCalculator implementation to be used to compare Resources in the scheduler. Maximum number of applications in the system which can be concurrently active both running and pending.Д¬.resource-calculator System-managed settings are not included. The Spark settings below are those that have BDC-specific defaults but are user configurable. Big Data Clusters-specific default Spark settings See Configure Apache Spark and Apache Hadoop in Big Data Clusters for instructions. To include Spark in the Storage pool, set the boolean value includeSpark in the bdc.json configuration file at .settings.spark. The settings we do not support configuring are also listed below.

You can find all possible configurations and the defaults for each at the associated Apache documentation site: Other than the gateway resource, there is no difference between settings that are configurable at the service scope and the resource scope. The settings that we do change are listed below along with a description and their default value. Big Data Clusters uses the same default configuration values as the respective open source project for most settings. For more information, see Big data options on the Microsoft SQL Server platform.Д«ig Data Clusters supports deployment time and post-deployment time configuration of Apache Spark and Hadoop components at the service and resource scopes. Support for SQL Server 2019 Big Data Clusters will end on February 28, 2025. The Microsoft SQL Server 2019 Big Data Clusters add-on will be retired.
