1. 猪：
Pig用于大量数据的分析。它是对 MapReduce 的抽象。 Pig 用于在 Hadoop 中执行各种数据操作操作。它提供了 Pig-Latin 语言来编写包含许多内置功能的代码，例如 join、filter 等。 Apache Pig 的两个部分是 Pig-Latin 和 Pig-Engine。 Pig Engine 用于将所有这些脚本转换为特定的地图并减少任务。 Pig 抽象处于更高级别。与 MapReduce 相比，它包含的代码行更少。
2.Hive：
Hive构建在 Hadoop 之上，用于处理 Hadoop 中的结构化数据。 Hive是由 Facebook 开发的。它提供了各种类型的查询语言，通常称为Hive查询语言。 Apache Hive是一个数据仓库，它在用户和集成了 Hadoop 的 Hadoop 分布式文件系统 (HDFS) 之间提供类似 SQL 的接口。
