    Below is the list of 11 features that answer – Why Hadoop?

    下面是 11 个功能的列表,这些功能回答了 Hadoop 的原因?

    1. Managing Big Data

    1. 驾驭大数据

    As we are living in the digital era there is a data explosion. The data is getting generated at a very high speed and high volume. So there is an increasing need to manage this Big Data.

    我们生活在数字时代、数据爆炸,数据以非常高的速度和体积生成. 因此,管理这些大数据的需求越来越大.

    Why Hadoop

    As we can see from the above chart that the volume of unstructured data is increasing exponentially. Therefore in order to manage this ever-increasing volume of data, we require Big Data technologies like Hadoop. According to Google from the dawn of civilization till 2003 mankind generated 5 exabytes of data. Now we produce 5 exabytes every two days. There is an increasing need for a solution which could handle this much amount of data. In this scenario, Hadoop comes to rescue.

    从上面的图表中我们可以看到,非结构化数据的数量呈指数级增长. 因此,为了管理不断增长的数据量,我们需要 大数据技术 像 Hadoop. 据谷歌 从文明的黎明到 2003年,人类产生了 5 exabytes 的数据.现在我们每两天生产 5 个亿字节.人们越来越需要一个能够处理如此大量数据的解决方案.在这种情况下,Hadoop 来救援.

    With its robust architecture and economical feature, it is the best fit for storing huge amounts of data. Though it might seem difficult to learn Hadoop, with the help of DataFlair Big Data Hadoop Course, it becomes easy to learn and start a career in this fastest growing field. So Hadoop must be learnt by all those professionals willing to start a career in big data as it is the base for all big data jobs.

    Hadoop 有一个非常强大和丰富的生态系统为各种各样的组织服务.像 web 初创企业、电信、金融等组织都需要 Hadoop 来满足他们的业务需求.

    Hadoop ecosystem contains many components like MapReduce, Hive, HBase, Zookeeper, Apache Pig etc. These components are able to serve a broad spectrum of applications. We can use Map-Reduce to perform aggregation and summarization on Big Data. Hive is a data warehouse project on the top HDFS. It provides data query and analysis with SQL like interface. HBase is a NoSQL database. It provides real-time read-write to large datasets. It is natively integrated with Hadoop. Pig is a high-level scripting language used with Hadoop. It describes the data analysis problem as data flows. One can do all the data manipulation in it with Pig. Zookeeper is an open source server that coordinates between various distributed processes. Distributed applications use zookeeper to store and convey updates to important configuration information.

    Hadoop 生态系统包含 MapReduce 、 Hive 、 HBase 、 Zookeeper 、 Apache Pig 等多个组件,这些组件能够服务于广泛的应用.我们可以使用地图缩小对大数据进行汇总汇总.Hive 是顶级 HDFS 上的一个数据仓库项目.它提供了类似 SQL 接口的数据查询和分析.一个 NoSQL 数据库.它提供对大型数据集的实时读写.它与 Hadoop 本身集成.Pig 是 Hadoop 中使用的高级脚本语言.它将数据分析问题描述为数据流.你可以用 Pig 做所有的数据操作.Zookeeper 是一个在各种分布式进程之间进行协调的开源服务器.分布式应用程序使用 zookeeper 来存储重要配置信息的更新.

    6. Research Tool

    6..研究工具

    Hadoop has come up as a powerful research tool. It allows an organization to find answers to their business questions. Hadoop helps them in research and development work. Companies use it to perform the analysis. They use this analysis to develop a rapport with the customer.

    Hadoop 已经成为一个强大的研究工具.它允许一个组织找到他们的业务问题的答案.Hadoop 帮助他们进行研发工作.公司用它来进行分析.他们利用这种分析与顾客建立融洽的关系.

    Applying Big Data techniques improve operational effectiveness and efficiencies of generating great revenue in business. It brings a better understanding of the business value and develops business growth.

    Creators of Hadoop have written it in Java, which has the biggest developer community. Therefore, it is easy to adapt by programmers. You can have the flexibility of programming in other languages too like C, C++, Python, Perl, Ruby etc. If you are familiar with SQL, it is easy to use HIVE. If you are ok with scripting then PIG is for you.

    Hadoop 的创建者用 Java 编写了它拥有最大的开发者社区.因此,程序员很容易适应.你也可以像 C,C + +,Python,Perl,Ruby 等其他语言的编程的灵活性.如果你熟悉 SQL,它很容易使用 HIVE.如果你对脚本没问题,那么 PIG 是给你的.

    Hadoop framework handles all the parallel processing of the data at the back-end. We need not worry about the complexities of distributed processing while coding. We just need to write the driver program, mapper and reducer function. Hadoop framework takes care of how the data gets stored and processed in a distributed manner. With the introduction of Spark in Hadoop, ecosystem coding has become even easier. In MapReduce, we need to write thousands of lines of code. But in Spark, it has come down to only a few lines of code to achieve the same functionality.

    Hadoop 框架处理后端数据的所有并行处理.在编码时,我们不需要担心分布式处理的复杂性.我们只需要编写驱动程序、映射程序和 reducer 函数就可以了.Hadoop 框架负责如何以分布式方式存储和处理数据.随着Hadoop 中 Spark 的介绍生态系统编码变得更加容易.在 MapReduce 中,我们需要编写数千行代码.但是在 Spark 中,实现相同功能的代码只有几行.

    8. Hadoop is Omnipresent

    8. Hadoop无处不在

    Why Hadoop is important

    There is no industry where Big Data has not reached. Big Data has covered almost all domains like healthcare, retail, government, banking, media, transportation, natural resources and so on. We can see this in the figure above. People are increasingly becoming data aware. This means they are realizing the power of data. Hadoop is a framework which can harness this power of data to improve the business.

    没有一个行业没有大数据.大数据已经覆盖了医疗、零售、政府、银行、媒体、交通、自然资源等几乎所有领域.我们可以在上图中看到这一点.人们越来越意识到数据.这意味着他们正在意识到数据的力量.Hadoop 是一个可以利用这种数据力量来改进业务的框架.

    Companies all over the world are trying to access information from various sources like social media. They are doing so in order to improve their performance and increase their revenue. Many organization face problem in processing heterogeneous data to extract value out of it. It has a capability to guide revolutionary transformation in research, invention and business marketing.
