The Hive Query Language (HiveQL) is a query language for Hive to process and analyze structured data in a Metastore. Apache Hive is a Data warehouse system that is built to work on Hadoop. It is used to querying and managing large datasets residing in distributed storage. Before becoming an open-source project of Apache Hadoop, Hive was originated in Facebook. It provides a mechanism to project structure onto the data in Hadoop and to query that data using a SQL-like language called HiveQL (HQL). Hive is used because the tables in Hive are similar to tables in a relational database. If you are familiar with SQL, it’s a cakewalk. Many users can simultaneously query the data using Hive-QL. 0:00 Data Types 6:43 Databases in HiveQL 16:34 Tables in HiveQL 42:05 Altering Tables in HiveQL 50:22 Partitioning Tables in HiveQL 1:05:03 Bucketing in HiveQL 1:14:08 HiveQL Operators 1:17:17 Built-in Functions in HiveQL 1:20:48 Group by and Having in HiveQL 1:27:24 Order by and sort by 1:29:42 Join in HiveQL

This video talks about how we can execute HDFS or linux level commands from hive terminal
This lecture is all about using Hive through Hive Shell which is a command line interface to run HiveQL queries to work with the big data stored in Hadoop (HDFS). We have seen how to create database, tables, loading data from a tab separated text file and running some basic aggregations to get meaningful insights out of our raw data file. In the previous lecture we have seen about running Hive queries on Hadoop through Ambari Web UI in which we have covered up basics of Hive and how we can run HiveQL queries using Hive View 2.0 on Ambari Web UI with ease. We have first created 2 tables Movies & Ratings, then using HiveQL we have analyzed and got the most popular movies in a dataset (Spoiler alert: * wars).

ATTENTION DATA SCIENCE ASPIRANTS: Click Below Link to Download Proven 90-Day Roadmap to become a Data Scientist in 90 Days 🤍 Apache Hive Beginner's Guide : 🤍 Apache Hive Courses : 🤍 In this video, you will get a quick overview of Apache Hive, one of the most popular data warehouse components on the big data landscape. It’s mainly used to complement the Hadoop file system with its interface. Hive was originally developed by Facebook and is now maintained as Apache hive by Apache software foundation. It is used and developed by biggies such as Netflix and Amazon as well. Why was Hive Developed = The Hadoop ecosystem is not just scalable but also cost effective when it comes to processing large volumes of data. It is also a fairly new framework that packs a lot of punch. However, organizations with traditional data warehouses are based on SQL with users and developers that rely on SQL queries for extracting data. It makes getting used to the Hadoop ecosystem an uphill task. And that is exactly why hive was developed. Hive provides SQL intellect, so that users can write SQL like queries called HQL or hive query language to extract the data from Hadoop. These SQL likes queries will be converted into map reduce jobs by the Hive component and that is how it talks to Hadoop ecosystem and HDFS file system. How and when Hive can be used? = Hive can be used for OLAP (online analytic) processing It is scalable, fast and flexible It is a great platform for the SQL users to write SQL like queries to interact with the large datasets that reside on HDFS filesystem Here is what Hive cannot be used for: It is not a relational database It cannot be used for OLTP (online transaction) processing It cannot be used for real time updates or queries It cannot be used for scenarios where low latency data retrieval is expected, because there is a latency in converting the HIVE scripts into MAP REDUCE scripts by Hive Some of the finest features of Hive It supports different file formats like sequence file, text file, avro file format, ORC file, RC file Metadata gets stored in RDBMS like derby database Hive provides lot of compression techniques, queries on the compressed data such as SNAPPY compression, gzip compression Users can write SQL like queries that hive converts into mapreduce or tez or spark jobs to query against hadoop datasets Users can plugin mapreduce scripts into the hive queries using UDF user defined functions Specialized joins are available that help to improve the query performance If you don’t understand any of the above terms, that is fine. We will look into the above features in detail in our upcoming videos.
This video talks about storing the output of hive query in file.
