Create a directory in which you can download and extract the hive tar.gz file. This document describes the steps you can take to install Apache Zeppelin on a CentOS 7 Machine. Previously, ETL was done with Python.ДЇollow the below steps to install Hive 2.x in CentOSДЎ. ETL support: ETL (Extract, Transform, and Load) is supported by Apache Hive.

Users can read and write data without having to think about where itвЂ™s processed, what format itвЂ™s in, or redefining the structure for each method.

Supports different Data Structures: Hive metadata is exposed to other data processing tools, such as Apache Pig and MapReduce, using HCatalog, a table and storage management layer for Hadoop.

Data Storage: Hive allows users to access files stored in HDFS, Apache HBase, Amazon S3, and other storage systems.

HiveQL is non-procedural since it is a declarative language, similar to SQL.

SQL-like Queries: Queries are written in HiveQL, a SQL-like language, and executed using MapReduce, Apache Tez, or Apache Spark, allowing more people to process and analyze massive quantities of data.

Step 6: Configure Virtual Hosts on CentOS 7 (optional) Apache Directories and Files. Following are some of the key features of Hive Step 5: Configure firewalld to Allow Apache Traffic. Hive is so powerful that it can query petabytes of data with ease. We use Hive on top of Hadoop to process the structured data available in tabular format. It has a SQL-like query language called HiveQL that translates queries to MapReduce, Apache Tez, and Spark jobs transparently. Though Apache Hive was created by Facebook, it is now used and produced by other companies such as Netflix.ДЄpache Hive allows you to analyze massive datasets stored in HadoopвЂ™s HDFS and compatible file systems like Amazon S3. Hive makes SQL-based applications more portable to Hadoop because most data warehouse systems use SQL-based querying languages. Hive gives the SQL abstract concept required to integrate SQL-like queries, also known as HiveQL, into the fundamental Java without needing queries to be incorporated in the low-level Java API.

In this article, we will look at how to install Apache Hive 2.x in CentOS. In order to execute SQL applications and queries over larger datasets, standard SQL queries must be used in the MapReduce Java API. Hive provides a SQL-like interface for querying data stored in Hadoop-integrated databases and file systems. Apache Hive is a data warehouse software project that provides data query and analysis on top of Apache Hadoop.
