Feed: Cloudera Engineering Blog. Author: Gabor Roczei. Background Authentication is a basic security requirement for any computing environment. In simple terms, users and services must prove their identity (authenticate) to the system before they can use system features. Kerberos provides strong authentication which is used in the exchange between requesting user or process and service during authentication. When a user authenticates to a particular Hadoop component, the user’s Kerberos principal is presented. The principal is presented in the form user@REALM. The Kerberos principal is mapped [1] to a short name after authentication. For example: user@EXAMPLE.COM --> user user@EXAMPLE.COM --> user ... Read More

Reverse proxying requests to a pgAdmin server is becoming more and more popular if posts to the mailing lists are to be taken as an indicative measure; more often than not when using pgAdmin in a container (of which there have now been over 10 million pulls)! Typically users will deploy a reverse proxy for a couple of reasons; to host multiple applications in different subdirectories under the same domain, or to add SSL/TLS support independently of the application.Because of the number of questions asked, I spent a little time over the last couple of days doing ...

Feed: Blog Post – Corporate – DataStax. Author: Patrick McFadin, VP of Developer Relations. Say what you’ll say about fads or trends, cloud is here to stay, and for many companies “the cloud” has now evolved into “hybrid cloud.” But most organizations didn’t expect to be in hybrid cloud, and now that they’re here their application developers are facing issues they’ve never faced before—issues that require a powerful, flexible, always-on database like Apache Cassandra to resolve.  But before we discuss why Cassandra is such an ideal database for hybrid cloud, we need to understand the how and the why of ...

Feed: AWS Big Data Blog. Customers often use Amazon Elasticsearch Service for log analytics. Amazon ES lets you collect logs from your infrastructure, transform each log line into a JSON document, and send those documents to the bulk API.A transformed log line contains many fields, each containing values. For instance, an Apache web log line includes a source IP address field, a request URL field, and a status code field (among others). Many users build dashboards—using Kibana—to monitor their infrastructure visually, surfacing application usage, bugs, or security problems evident from the data in those fields. For example, you can graph ... Read More
