  • PROCESSING LARGE / BIG DATA SET THROUGH Mapr and PIG
    International Journal of Scientific & Engineering Research Volume 8, Issue 7, July-2017 863 ISSN 2229-5518 PROCESSING LARGE / BIG DATA SET THROUGH MapR AND PIG Arvind Kumar-Senior ERP Solution Architect / Manager, Derex Technologies, Inc. Abstract : We live in the data age. It’s not easy to measure the total volume of data stored electronically, but an IDC estimate put the size of the “digital universe” at 0.18 zettabytes in 2006, and is forecasting a tenfold growth by 2011 to 1.8 zettabytes.* A zettabyte is 1021 bytes, or equivalently one thousand Exabyte’s, one million petabytes, or one billion terabytes. That’s roughly the same order of magnitude as one disk drive for every person in the world. MapReduce is a programming model for data processing. The model is simple, yet nottoo simple to express useful programs in. Hadoop can run MapReduce programs writtenin various languages, MapReduce programs are inherentlyparallel, thus putting very large-scale data analysis into the hands of anyone withenough machines at their disposal. MapReduce comes into its own for large datasets. MapReduce is a framework for performing distributed data processing using the MapReduce programming paradigm. In the MapReduce paradigm, each job has a user-defined map phase, which is a parallel, share-nothing processing of input; followed by a user-defined reduce phase where the output of the map phase is aggregated). Pig raises the level of abstraction for processing large datasets. With MapReduce, thereis a map function and there is a reduce function, and working out how to fit your data processing into this pattern, which often requires multiple MapReduce stages, can be a challenge.

  • From Apache Hadoop/Spark to Amazon EMR: Best Migration Practices and Cost Optimization Strategies Executive Summary
    From Apache Hadoop/Spark to Amazon EMR: Best Migration Practices and Cost Optimization Strategies Executive Summary As more businesses look to technologies like machine learning and predictive analytics to more efficiently drive business outcomes, they seek to migrate on-premises Apache Spark and Hadoop clusters to the cloud. Wrestling with rising costs, maintenance uncertainties and administrative headaches, they turn to Amazon Elastic MapReduce (EMR) to support Big Data, Spark, and Hadoop environments. Amazon EMR is a cost-efficient, high-performance service that improves business agility and keeps down resource utilization costs. As a foundation for building data streaming and machine learning infrastructure, EMR enables organizations to transform into AI-driven enterprises, to become better at targeting prospects, supporting customers, building effective products, and responding to market needs. This whitepaper will walk you through Amazon EMR’s key features, look into its business and technology benefits, and explore core scenarios for migrating Apache Spark & Hadoop clusters to Amazon EMR: Hadoop on-prem to EMR on AWS through Lift & Shift or Re-Architect Next-Gen architecture on AWS — Containers, non-HDFS, or Streaming Existing Hadoop on-prem to Hadoop on AWS through Rehost, Replatform or Redistribution We will also look into major cost optimization strategies with Amazon EMR for businesses running workloads on Apache Hadoop and Apache Spark. 2 Amazon EMR Overview Amazon EMR is the industry-leading cloud-native Big Data platform for improving resource utilization by Apache Hadoop, Hive, Spark, Map/Reduce, and machine learning workloads. Designed to process vast amounts of data quickly and cost-effectively at scale, it is powered by open-source tools such as Apache Spark, Apache Hive, Apache HBase, Apache Flink, Apache Hudi and Presto, coupled with Amazon EC2 and Amazon S3.

  • Implementation of Hadoop -2
    Implementation of Hadoop -2 Kiranmayi Ganti Performance and Scalability . Data Ingest Using Streaming Writes • MapR uses Spark Streaming to ingest real time data. • Spark Streaming is an extension of the core Spark API that allows enables high- throughput, fault-tolerant stream processing of live data streams. • Data can be ingested from many sources like Kafka, Flume, Twitter, ZeroMQ or plain old TCP sockets and be processed using complex algorithms expressed with high-level functions like map, reduce and join. • Finally, processed data can be pushed out to file systems, databases, and live dashboards. In fact, you can apply Spark’s in-built machine learning algorithms, and graph processing algorithms on data streams. SPARK API Hbase Performance • HBase is an open source, non-relational, distributed database modeled after Google's BigTable and written in Java. It is developed as part of Apache Software Foundation's Apache Hadoop project and runs on top of HDFS (Hadoop Distributed Filesystem), providing Big Table-like capabilities for Hadoop. That is, it provides a fault-tolerant way of storing large quantities of sparse data. • Latency • Consistent low latency Dependability Manageability Ambari • The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. • Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs. Volume Support-I • The MapR File System uses volumes as a unique management entity. • A volume is a logical unit that you create to apply policies to a set of files, directories, tables, and sub-volumes. • You can create volumes for each user, department, or project.
