Accumulo Summit 2015: Ambari and Accumulo: HDP 2.3 Upcoming Features [Sponsored]Accumulo Summit
Talk Abstract
The upcoming Hortonworks Data Platform (HDP) 2.3 includes significant additions to Accumulo, within the project itself and in its interactions with the larger Hadoop ecosystem.This session will cover high-level changes that improve usability, management and security of Accumulo. Administrators of Accumulo now have the ability to deploy, manage and dynamically configure Accumulo clusters using Apache Ambari.As a part of Ambari integration, the metrics system in Accumulo has been updated to use the standard “Hadoop Metrics2” metrics subsystem which provides native Ganglia and Graphite support as well as supporting the new Ambari Metrics System. On the security front,Accumulo was also improved to support client authentication via Kerberos, while earlier versions of Accumulo only supported Kerberos authentication for server processes.With these changes,Accumulo clients can authenticate solely using their Kerberos identity across the entire Hadoop cluster without the need to manage passwords.
Speakers
Billie Rinaldi Senior Member of Technical Staff, Hortonworks
Billie Rinaldi is a Senior Member of Technical Staff at Hortonworks, Inc., currently prototyping new features related to application monitoring and deployment in the Apache Hadoop ecosystem. Prior to August 2012, Billie engaged in big data science and research at the National Security Agency. Since 2008, she has been providing technical leadership regarding the software that is now Apache Accumulo. Billie is the VP of Apache Accumulo, the Accumulo Project Management Committee Chair, and a member of the Apache Software Foundation. She holds a Ph.D. in applied mathematics from Rensselaer Polytechnic Institute.
Josh Elser Member of Technical Staff, Hortonworks
Josh is a member of the engineering staff at Hortonworks. He is strong advocate for open source software and is an Apache Accumulo committer and PMC member. He is also a committer and PMC member of Apache Slider (incubating) and regularly contributes to other Apache projects in the Apache Hadoop ecosystem. He holds a Bachelor's degree in Computer Science from Rensselaer Polytechnic Institute.
The document discusses editing images for a magazine layout. The author increased the exposure on a main image of artists performing. They also tried coloring one image red and blue in Photoshop, deciding blue looked better and was unique. When unsure how to wrap text around images in InDesign, the author watched a YouTube tutorial, which helped them apply the technique to a pull quote. The author further edited an image in Photoshop by cropping out a female model to better represent the band discussed.
Through constructing this product, I have learned about digital photography and image editing technologies. I used a Sony CyberShot camera to take pictures for my magazine. I then edited all three of my products - the front cover, contents page, and double page spread - using Adobe Photoshop. Photoshop proved to be a valuable program for editing despite initial complexity, as tutorials helped me learn its features. These include refining image edges and layer functionality for easy editing.
The document discusses innovations in supply chain management. It makes three key points:
1. While new technologies and concepts allow for greater supply chain insights and responsiveness, many organizations struggle to implement innovations effectively due to unclear strategies and contradictory goals.
2. An integral model is proposed to better translate organizational strategies into supply chain strategies, focusing on nine levers of value like financial parameters, business models, and operational excellence.
3. Games and workshops can help organizations gain a shared understanding of how operational choices impact overall performance and identify supply chain priorities like costs, quality, lead times, and flexibility.
Presentation about "Terror and terrorism in ancient Rome" containing references and links to articles written by eminent scholars as Adalberto Giovannini and Alberto Grilli for the meeting held in 2005 at Cividale del Friuli by Fondazione Canussio, entitled "Terror et pavor- Violenza, intimidazione, clandestinità nel mondo antico".

Ceph Day Berlin: CEPH@DeutscheTelekom - a 2+ years production liaison Ceph Community
Deutsche Telekom has been using Ceph in production for object storage and block storage via OpenStack since 2013. They currently have multiple Ceph clusters with a total raw capacity of 4.8PB spread across approximately 60 storage nodes. They are planning a scale out project to increase capacity to 7.5PB across approximately 90 storage nodes by distributing replicas across different rooms and racks for high availability. Their experience with Ceph in production has shown that hardware selection, capacity planning, and tuning configurations like the number of PGs are important factors for performance and reliability.
Control of Dvr with Battery Energy Storage System Using Srf TheoryIJERA Editor
One of the best solutions to improve power quality is the dynamic voltage restorer (DVR). DVR is a kind of
custom power devices that can inject active/reactive power to the power grids. This can protect loads from
disturbances such as sag and swell. Usually DVR installed between sensitive loads feeder and source in
distribution system. Its features include lower cost, smaller size, and its fast dynamic response to the
disturbance. In this project SRF technique is used for conversion of voltage from rotating vectors to the
stationary frame. SRF technique is also referred as park’s transformation. In this the reference load voltage is
estimated using the unit vectors. The real power exchanged at the DVR output ac terminal is provided by the
DVR input dc terminal by an external energy source or energy storage system. In this project three phase
parallel or series load may be used along with SRF technique to compensate voltage sag and voltage swell. And
also wind generator is also used as a load. This project presents the simulation of DVR system using
MATLAB/SIMULINK.
This document summarizes a presentation on scaling academic clouds with Ceph. It discusses the software-defined datacenter and how Ceph can manage cloud resources and work with OpenStack. Two university Ceph deployments are described: a collaboration between 4 UK universities using Ceph for a microbial bioinformatics cloud, with 6.9PB of total capacity across the sites; and a deployment at the University of Zurich with 4.2PB of high-capacity tier storage and 112TB of high-performance SSD storage to provide block access for scientific applications. The presentation covers considerations for infrastructure like storage nodes, networks, and datacenters, and references a Dell/Inktank Ceph reference architecture providing hardware, software, and services.
