AWS Glue is a serverless data integration service that makes it easy for analytics users to discover, prepare, move, and integrate data from multiple sources. You can use it for analytics, machine learning, and application development. It also includes additional productivity and data ops tooling for authoring, running jobs, and implementing business workflows. With AWS Glue, you can discover and
Extracting, transforming and selecting features This section covers algorithms for working with features, roughly divided into these groups: Extraction: Extracting features from “raw” data Transformation: Scaling, converting, or modifying features Selection: Selecting a subset from a larger set of features Locality Sensitive Hashing (LSH): This class of algorithms combines aspects of feature trans

Spark シェルは、Scala REPL (Read-Eval-Print-Loop) がベースになっています。このシェルを使用すると、Spark プログラムをインタラクティブに作成し、作業をフレームワークに送信できます。Spark シェルには、SSH を使用してプライマリノードに接続し、spark-shell を呼び出すことでアクセスできます。プライマリノードへの接続の詳細については、「Amazon EMR 管理ガイド」の「Connect to the primary node using SSH」を参照してください。次の例では、Amazon S3 に格納された Apache HTTP Server アクセスログを使用します。
Quick Start Interactive Analysis with the Spark Shell Basics More on Dataset Operations Caching Self-Contained Applications Where to Go from Here This tutorial provides a quick introduction to using Spark. We will first introduce the API through Spark’s interactive shell (in Python or Scala), then show how to write applications in Java, Scala, and Python. To follow along with this guide, first, do
ML Pipeline APIs¶ DataFrame-based machine learning APIs to let users quickly assemble and configure practical machine learning pipelines. class pyspark.ml.Transformer¶ Abstract class for transformers that transform one dataset into another. copy(extra=None)¶ Creates a copy of this instance with the same uid and some extra params. The default implementation creates a shallow copy using copy.copy(),
