Hadoop has been widely adopted by organizations for various use cases. One of its key use cases is in storing and analyzing log data, financial data from systems like JD Edwards, and retail catalog and session data for an omnichannel experience. Users have found that Hadoop's distributed processing capabilities allow for efficient and cost-effective storage and analysis of large amounts of data. It has been particularly helpful in reducing storage costs and improving performance when dealing with massive data sets. Furthermore, Hadoop enables the creation of a consistent data store that can be integrated across platforms, making it easier for different departments within organizations to collect, store, and analyze data. Users have also leveraged Hadoop to gain insights into business data, analyze patterns, and solve big data modeling problems. The user-friendly nature of Hadoop has made it accessible to users who are not necessarily experts in big data technologies. Additionally, Hadoop is utilized for ETL processing, data streaming, transformation, and querying data using Hive. Its ability to serve as a large volume ETL platform and crunching engine for analytical and statistical models has attracted users who were previously reliant on MySQL data warehouses. They have observed faster query performance with Hadoop compared to traditional solutions. Another significant use case for Hadoop is secure storage without high costs. Hadoop efficiently stores and processes large amounts of data, addressing the problem of secure storage without breaking the bank. Moreover, Hadoop enables parallel processing on large datasets, making it a popular choice for data storage, backup, and machine learning analytics. Organizations have found that it helps maintain and process huge amounts of data efficiently while providing high availability, scalability, and cost efficiency. Hadoop's versatility extends beyond commercial applications—it is also used in research computing clusters to complete tasks faster using the MapReduce framework. Finally, the Systems and IT department relies on Hadoop to create data pipelines and consult on potential projects involving Hadoop. Overall, the use cases of Hadoop span across industries and departments, providing valuable solutions for data collection, storage, and analysis.

Hadoop is used by data center management team. Hadoop processes the metric data pushed by virtual machines. Hadoop's output is served to the analytics engine and respective actions are taken to maintain even load on machines.
  • Processing huge data sets.
  • Concurrent processing.
  • Performance increases with distribution of data across multiple machines.
  • Better handling of unstructured data.
  • Data nodes and processing nodes
  • Make Haadop lighweight.
  • Installation is very difficult. Make it more user friendly.
  • Introduce a feature that works with continuous integration.
Ask about how Hadoop fits in your environment and how fast it processes streaming data.
Hadoop has a master slave architecture and comes with more features than Splunk.

We are using it for Retail data ETL processing. This is going to be used in whole organization. It allows terabytes of data to be processed in faster manner with scalability.
  • Processes big volume of data using parallelism in faster manner.
  • No schema required. Hadoop can process any type of data.
  • Hadoop is horizontally scalable.
  • Hadoop is free.
  • Development tools are not that friendly.
  • Hard to find hadoop resources.
Hadoop is not a replacement of a transactional system such as RDBMS. It is suitable for batch processing.
  • None
Volume , velocity and variety. Also it is free.
  • You dont need to pay a heavy licensing fee for Hadoop. You save money.
  • It is open source technology so some times you need to purchase support from Cloudera or Hortonworks.

  • Implemented in-house
Change management was a small part of the implementation and was well-handled

Hadoop is used for storing and analyzing log data (logs from warehouse loads or other data processing) as well as storing and retrieving financial data from JD Edwards. It's also planned to be used for archival. Hadoop is used by several departments within our organization. Currently, we are paying a lot of money for hosting historical data and we plan to move that to Hadoop; reducing our storage costs. Also, we got a much better performance out of our Hadoop cluster for processing a large amount of financial data. So, in that senese, Hadoop addressed multiple business problems for us.
  • Hadoop stores and processes unstructured data such as web access logs or logs of data processing very well
  • Hadoop can be effectively used for archiving; providing a very economic, fast, flexible, scalable and reliable way to store data
  • Hadoop can be used to store and process a very large amount of data very fast
  • Security is a piece that's missing from Hadoop - you have to supplement security using Kerberos etc.
  • Hadoop is not easy to learn - there are various modules with little or no documentation
  • Hadoop being open-source, testing, quality control and version control are very difficult
Hadoop is best suited for warehouse or OLAP processing. It's not suitable for OLTP or small transaction processing
  • We had a large ROI due to improved performance and expedited reporting - our clients were happier and business improved
  • Our storage costs reduced
  • Our infrastructure costs reduced - we used old hardware for our Hadoop cluster
not applicable - I have not evaluated any other products

  • Use of HDFS / Hive for storage / analysis of data processing logs
  • Use of HDFS / Hive for storage / analysis of historical financial data
  • Use of HDFS for Archival
  • Archival
  • Reporting
  • ETL
  • Data transfer
  • Staging area
  • Historical reporting
Hadoop is organization-independent and can be used for various purposes ranging from archiving to reporting and can make use of economic, commodity hardware. There is also a lot of saving in terms of licensing costs - since most of the Hadoop ecosystem is available as open-source and is free
Yes
We replaced 5 Windows based servers by a 10 node CentOS based desktops. Saved a lot on hardware and Windows server licenses
  • Price

  • Product Usability
Price. We saved a lot of money
I will evaluate the ROI more closely
Hadoop is a complex topic and best suited for classrom training. Online training are a waste of time and money.

It was used by a department
  • Definitely speed up data processing efforts
  • I think certain design patterns should be more recommended than others.
Any batch or bulk processing - certainly recommended. Single transaction processing needed real time - not sure, might have issues with such.
  • faster data processing
100
I think it is a great technology.
