Course Description

Hive on top of Hadoop as its data warehouse framework for querying and analysis of data stored in HDFS. A hive is an open-source software. That lets programmers analyze large data sets on Hadoop. The performing operations like data encapsulation, ad-hoc queries, and analysis datasets

The hive’s design reflects use as a system for managing and querying structured data. Structured data in general, Map Reduce doesn’t have optimization and usability features. Hive's SQL- language separates from the complexity of Map-Reduce programming. It re-uses concepts from the relational database world. Such as tables, rows, columns, and schema, too easy learn

    Hive Architecture

     There are 3 major components in Hive as shown in the architecture diagram. They are hive clients and services stored in Meta Store. Under hive client, we can have different ways to connect to HIVE SERVER in hive services.

    These are Thrift client, ODBC driver, and JDBC driver. It provides an easy environment to execute the hive commands from programming languages. Thrift client bindings for Hive are available for C++, Java, PHP scripts, python scripts and Ruby. JDBC and ODBC drivers for communication between client and servers for compatible options.
     

    1.HIVESERVER

     HIVESERVER is an API. That allows the clients to execute the queries on data warehouse and get the desired results. The services driver, compiler, and execution engine interact with each other.


    The client submit

     The client submits the query via a GUI. The driver receives the queries in the first instance from GUI. It will define session handlers, which will fetch required APIs. Different interfaces like JDBC or ODBC. The compiler creates the plan for the job to execute. The compiler, in turn, is in contact with matter and it gets metadata from Meta Store.

    Execution Engine

    Execution Engine (EE) is the key component. To execute a query by communicating with Job Tracker, Name Node, and Data nodes. As discussed earlier, by running hive query at the backend, it will generate a series of MR Jobs. The execution engine plays like a bridge between hive and Hadoop to process the query.

    At the end, EE is going to desired results from Data Nodes. EE will be having bi-directional communication with Metastore. In the hive, the side is a framework to serialize and de-serialize input and output data from HDFS to local.

    Metastore used for collection of all the metadata. It’s having backup services to backup Meta store info. The service runs on the JVM as the services of hive running on. The structural information of tables, columns, information stored in this.
