# Now just run the pyspark executable and you are ready to go with NXCALS using # default configuration: running Spark in local mode with default Spark properties # including minimal amount of memory for Spark driver (venv ) $ pyspark PySpark and Scala Spark execution contexts are supported by those bundles. Providing a bootstrapped instance of Spark with all the needed configuration to connect on-the-fly to a target NXCALS environment. Those bundles contain a pre-configured spark instance, with a single goal in mind: There is where the NXCALS bundles come very handy. Those actions remain common between different user cases, since they have to be applied for any operation that requires data access via a Spark context. The first set of actions (outside of the context of spark) are considered as prerequisites for Spark configuration.

Basic YARN configuration (optionally for yarn mode execution).

Effective Spark properties configuration.

Python execution environment configuration (for PySpark).

NXCALS data access client module and its dependencies schema.

Location of the API services and brokers.

Hadoop cluster that NXCALS is running (configuration for connecting).

Here are some of the elements that have to be taken into account besides registration and authentication: Configuring a vanilla Spark instance for NXCALS data access requires a brief knowledge of the infrastructure

The NXCALS ecosystem contains many different environments and systems. KeyValuesQuery and VariableQuery were unified into 'DataQuery', accessible via byEntities() and byVariables() respectively.DevicePropertyQuery has been renamed to DevicePropertyDataQuery.java builders were moved from .builders to .data.builders.python builders were moved from to .builders.Working with snapshots and variable lists Setting up your virtual environment for running pySpark:Įxample of PySpark session when using NXCALS Spark bundle:
