The Spark ecosystem Apache Spark, the largest open-source project in data processing, is the only processing framework that combines data andartificial intelligence (AI). This enables users to perform large-scale data transformations and analyses, and then run state-of-the-art machine learning (ML...
Spark可以运行在Hadoop的YARN、Mesos, standalone,或者运行在云上。 Spark 处理的数据,可以存储在HDFS, Cassandra, HBase,和S3等等。 Spark的发展非常快速,TimeLine如下 Spark进入Apache后,发展非常迅速。版本发布比较频繁。 MapReduce属于Hadoop生态体系之一,Spark则属于BDAS生态体系之一 ...
SparkSession 在Spark 2.0 中,引入了一个新类 org.apache.spark.sql.SparkSession 来使用,它是我们在2.0发布之前拥有的所有不同上下文(SQLContext 和 HiveContext 等)的组合类,因此 SparkSession 可以用于替换 SQLContext 、HiveContext 以及2.0 之前定义的其他上下文。
