Spark | openEuler

Current MLflow docker images are built on the openEuler. This repository is free to use and exempted from per-user rate limits.
Apache Spark is a multi-language engine for executing data engineering, data science, and machine learning on single-node machines or clusters. It provides high-level APIs in Scala, Java, Python, and R, and an optimized engine that supports general computation graphs for data analysis. It also supports a rich set of higher-level tools including Spark SQL for SQL and DataFrames, pandas API on Spark for pandas workloads, MLlib for machine learning, GraphX for graph processing, and Structured Streaming for stream processing.

  复制代码
• Interactive Scala Shell
  The easiest way to start using Spark is through the Scala shell:
  
  1. docker run -it --name spark openeuler/spark:{Tag} /opt/spark/bin/spark-shell

  复制代码
  Try the following command, which should return 1,000,000,000:
  
  1. scala> spark.range(1000 * 1000 * 1000).count()

  复制代码
  
  
  
• Interactive Python Shell
  The easiest way to start using PySpark is through the Python shell:
  
  1. docker run -it --name spark openeuler/spark:{Tag} /opt/spark/bin/pyspark

  复制代码
  And run the following command, which should also return 1,000,000,000:
  
  1. >>> spark.range(1000 * 1000 * 1000).count()
