Learn how Spark facilitates the calculation of computationally-intensive statistics such as VaR via the Monte Carlo method.
Under reasonable circumstances, how much money can you expect to lose? The financial statistic value at risk (VaR) seeks to answer this question. Since its development on Wall Street soon after the stock market crash of 1987, VaR has been widely adopted across the financial services industry. Some organizations report the statistic to satisfy regulations,
Using an appropriate network representation and the right tool set are the key factors in successfully merging structured and time-series data for analysis.
In Part 1 of this series, you took your first steps for using Apache Giraph, the highly scalable graph-processing system, alongside Apache Hadoop. In this installment, you’ll explore a general use case for analyzing time-dependent, Big Data graphs using data from multiple sources.
Our thanks to Don Drake (@dondrake), an independent technology consultant who is currently working as a Principal Big Data Consultant at Allstate Insurance, for the guest post below about his experiences with Impala.
It started with a simple request from one of the managers in my group at Allstate to put together a demo of Tableau connecting to Cloudera Impala. I had previously worked on Impala with a large dataset about a year ago while it was still in beta,
Did you know that using the Crunch API is a powerful option for doing time-series analysis?
Apache Crunch is a Java library for building data pipelines on top of Apache Hadoop. (The Crunch project was originally founded by Cloudera data scientist Josh Wills.) Developers can spend more time focused on their use case by using the Crunch API to handle common tasks such as joining data sets and chaining jobs together in a pipeline.
Our thanks to Amar Parkash, a Software Developer at Goibibo, a leading travel portal in India, for the enthusiastic support of Hue you’ll read below.
At Goibibo, we use Hue in our production environment. I came across Hue while looking for a near real-time log search tool and got to know about Cloudera Search and the interface provided by Hue. I tried it on my machine and was really impressed by the UI it provides for Apache Hive,
