    Tales from the Cloudera Field
    • Monday, May 05 2014
    • Category: Presentation Slides, HBaseCon
    From supporting the 0.90.x, 0.92, 0.94, and 0.96 HBase installations on clusters ranging from tens to hundreds of nodes, Cloudera has seen it all. Having automated the upgrade paths from the different Apache releases, we have developed a smooth path that can help the community with upcoming upgrades. In addition to automation best practices, in this talk you'll also learn proactive configuration tweaks and operational best practices to keep your HBase cluster always up and running. We'll also walk through how to contain an application bug let loose in production, to minimize the impact on HBase posed by faulty hardware, and the direct correlation between inefficient schema design and HBase performance.

    Bulk Loading in the Wild: Ingesting the World's Energy Data
    • Monday, May 05 2014
    • Category: CDH, Presentation, Video
    HBase is designed to store your big data and provide low latency random access to that data. One of its most compelling features is Bulk Loading, which enables the generation of HFiles that can then be passed to the RegionServers. Opower's energy insights platform uses it to ingest the hundreds of millions of meter reads it receives daily from its partner utility companies. This presentation will walk you through the HBase Bulk Loading process and Opower's adoption of it as an important piece of its HBase ecosystem.

    HBase Read High Availability Using Timeline-Consistent Region Replicas
    • Monday, May 05 2014
    • Category: HBaseCon, Presentation Slides
    HBase has ACID semantics within a row that make it a perfect candidate for a lot of real-time serving workloads. However, single homing a region to a server implies some periods of unavailability for the regions after a server crash. Although the mean time to recovery has improved a lot recently, for some use cases, it is still preferable to do possibly stale reads while the region is recovering. In this talk, you will get an overview of our design and implementation of region replicas in HBase, which provide timeline-consistent reads even when the primary region is unavailable or busy.

    New Security Features in Apache HBase 0.98: An Operator's Guide
    • Monday, May 05 2014
    • Category: HBaseCon, Presentation Slides
    HBase 0.98 introduces several new security features: visibility labels, cell ACLs, transparent encryption, and coprocessor framework changes. This talk will cover the new capabilities available in HBase 0.98+, the threat models and use cases they cover, how these features stack up against other data stores in the Apache big data ecosystem, and how operators and security architects can take advantage of them.
