Learn how Cloudera Navigator Encrypt bring data security to YARN containers.
With the introduction of transparent data encryption in HDFS, we are now a big step closer toward a secure platform in the Apache Hadoop world. However, there are still gaps in the platform, including how YARN and its applications manage their cache. In this post, I’ll explain how Cloudera Navigator Encrypt fills that particular gap.
When a YARN application runs in a cluster it can sometimes spill data to the hard disk,
Thrift client authentication and doAs impersonation, introduced in HBase 1.0, provides more flexibility for your HBase installation.
In the two-part blog series “How-to: Use the HBase Thrift Interface” (Part 1 and Part 2), Jesse Anderson explained the Thrift interface in detail, and demonstrated how to use it. He didn’t cover running Thrift in a secure Apache HBase cluster, however, because there was no difference in the client configuration with the HBase releases available at that time.
Cloudera Navigator Encrypt is a key security feature in production-deployed enterprise data hubs. This post explains how it works.
Cloudera Navigator Encrypt, which is integrated with Cloudera Navigator (the native, end-to-end governance solution for Apache Hadoop-based systems), provides massively scalable, high-performance encryption for critical Hadoop data. It utilizes industry-standard AES-256 encryption and provides a transparent layer between the application and filesystem. Navigator Encrypt also includes process-based access controls,
Learn about the design decisions behind HBase’s new support for MOBs.
Apache HBase is a distributed, scalable, performant, consistent key value database that can store a variety of binary data types. It excels at storing many relatively small values (<10K), and providing low-latency reads and writes.
However, there is a growing demand for storing documents, images, and other moderate objects (MOBs) in HBase while maintaining low latency for reads and writes.
Apache Hive 1.2.0, although not a major release, contains significant improvements.
Recently, the Apache Hive community moved to a more frequent, incremental release schedule. So, a little while ago, we covered the Apache Hive 1.0.0 release and explained how it was renamed from 0.14.1 with only minor feature additions since 0.14.0.
Shortly thereafter, Apache Hive 1.1.0 was released (renamed from Apache Hive 0.15.0), which included more significant features—including Hive-on-Spark.
