An Introduction to Apache Hive

Apache Hive is an open source data warehouse software project for providing data summarization, query, and analysis where the large data sets are principally stored in Hadoop files. It offers a lucid way to apply structure to a huge amount of unstructured data and execute batch SQL like queries on that data. Most of the students due to lack of time often seek help from BookMyEssay for getting Apache Hive assignment help.

Apache Hive – An Overview

Apache Hive supports analysis of large data-sets stored in Hadoop Distributed file system (HDFS) and compatible file systems like Amazon S3. Hive has three main functions: data summarization, query, and analysis. It supports queries expressed in the language called HiveQL, an asserting SQL-like language which transparently converts queries to MapReduce, Apache Tez, and Spark Jobs. All three execution engines can work in Hadoop YARN. To facilitate queries, it provides indexes, including bitmap indexes, which are considered to work well with low cardinality columns. Other features of Hive include different storage type for e.g. plain text, RC File and HBase. The experts of Apache Hive thesis paper writing help keep upgraded knowledge in all the above-mentioned aspects of Apache Hive.

Metadata storage in a corresponding database management system, operating on Compressed Data stored into the Hadoop Ecosystem and in-built user-defined functions to manipulate dates, strings and other data mining tools aids in the practicality of Apache Hive.

Hive Architecture

Understanding the architecture is imperative for the comprehensive knowledge and efficient assignment writing in any topic of Apache Hive. Apache Hive homework assignment help online experts keep in-depth knowledge of Hive Architecture.

Major components of the Hive architecture are:

• Metascore: Metadata for each of the tables are stored as per their scheme and location.
• Driver: Controller which receives the HiveQL statements.
• Compiler: Compilation of HiveQL query which is eventually converted to execute a plan.
• Optimizer: Performs various transformations on the execution plan to get an optimized Directed Acyclic Graph, DAG.
• Executor: once the process of compilation and optimization is finished, to schedule tasks to be run, the executor interacts with the job tracker of Hadoop.
• CLI, UI, and Thrift Server: A user interface (UI) for an extraneous user to interact with Hive by submitting queries, instructions and supervising the process status is offered by the Command-line interface (CLI). Over a network, Thrift server permits external clients to interact with Hive, homogeneous to the ODBC protocols or JDBC.

Comparison with Traditional Databases

There is a close resemblance of Hive with that of traditional databases in terms of storage and querying operations. However, the main difference is Hive depends upon Hadoop ecosystem and has to comply with the restrictions of Hadoop and MapReduce. While traditional bases follow Schema on reading, Hive follows Schema on write. Extra overhead is added while checking data against table schema during the load time, resulting in traditional databases taking a longer time to load data. Whereas, Hive ensures a fast-initial load as it loads data dynamically without any schema check.

Hive Supporters

Apache Hive is used and developed by companies such as Netflix and the Financial Industry Regulatory Authority (FINRA), though originally developed by Facebook. Amazon maintains a software fork of Apache Hive included in Amazon Elastic MapReduce on Amazon Web Services. Committers to the Apache Hive community project have included individuals from Cloudera, Hortonworks, LinkedIn, Databricks and others as well. Hive is supported in Hadoop distribution and is available by download from the Apache Foundation, as well as from Hadoop distribution providers such as Cloudera, MapR, and Hortonworks, and as a part of AWS Elastic MapReduce. Students who are engaged in the study of such topics are eventually allocated to complete their assignment writing on Apache Hive task ontime.

Hive Security

Hive v0.7.0 added integration with Hadoop security. It uses Kerberos authorization support for security which allows for mutual authentication between client and server.

There are many other interesting aspects of Hive. It is hard to predict what kinds of topics you will get in the next assignment. Better to stay in touch with BookMyEssay’s Apache Hive assignment writing help.
