Securing Apache Spark Shuffle using Apache Commons Crypto

Categories: Guest Security Spark

Learn how the performance advantages of the Crypto cryptographic library will provide an upgrade for Spark shuffle encryption over the current approach.

When running a big data computing job, the data being processed may contain sensitive information that users don’t want anyone else to access. Encrypting that sensitive data is becoming more and more important, especially for enterprise users.

For Apache Spark, which is the emerging standard for big data processing,

New Study: Evaluating Apache HBase Performance on Modern Storage Media

Categories: Guest Hardware HBase Performance

For the first time, this new study by Intel software engineers analyzes the performance impact of using Apache HBase on various modern storage technologies.

As more “fast” storage technologies (such as SSD and NVMe SSD) emerge, organizations with big data use cases want to make better use of them to achieve better throughput and latency. But to this point, there have been no detailed analyses published about the true significance of that performance boost,

How-to: Process and Index Medical Images with Apache Hadoop and Apache Solr

Categories: CDH Guest Search Use Case ZooKeeper

Thanks to Karthik Vadla, Abhi Basu, and Monica Martinez-Canales of Intel Corp. for the following guest post about using CDH for cost-effective processing/indexing of DICOM (medical) images.

Medical imaging has rapidly become the best non-invasive method to evaluate a patient and determine whether a medical condition exists. Imaging is used to assist in the diagnosis of a condition and, in most cases, is the first step of the journey through the modern medical system.
