Jeff Zhang is a committer for Apache Tez and Hortonworks employee. He gave a presentation on Tez introducing it as a next generation execution engine for Hadoop. Tez uses a directed acyclic graph (DAG) to express computations and optimize jobs by executing multiple tasks simultaneously. It allows data sharing between jobs and dynamic resource allocation.

Speed Up Your Queries with Hive LLAP Engine on Hadoop or in the Cloudgluent.
Hive was the first popular SQL layer built on Hadoop and has long been known as a heavyweight SQL engine suitable mainly for long-running batch jobs. This has greatly changed since Hive was announced to the world over 8 years ago. Hortonworks and the open source community have evolved Apache Hive into a fast, dynamic SQL on Hadoop engine capable of running highly concurrent query workloads over large datasets with sub-second response time.
The latest Hortonworks and Azure HDInsight platform versions fully support Hive with LLAP execution engine for production use. In this webinar, we will go through the architecture of Hive + LLAP engine and explain how it differs from previous Hive versions. We will then dive deeper and show how features like query vectorization and LLAP columnar caching bring further automatic performance improvements.
In the end, we will show how Gluent brings these new performance benefits to traditional enterprise database platforms via transparent data virtualization, allowing even your largest databases to benefit from all this without changing any application code. Join this webinar to learn about significant improvements in modern Hive architecture and how Gluent and Hive LLAP on Hortonworks or Azure HDInsight platforms can accelerate cloud migrations and greatly improve hybrid query performance!

We share our slides about Apache Tez delivered as a lightening talk given at Warsaw Hadoop User Group http://www.meetup.com/warsaw-hug/events/218579675
Apache Hive has been continuously evolving to support a broad range of use cases, bringing it beyond its batch processing roots to its current support for interactive queries with sub-second response times using LLAP. However, the development of its execution internals is not sufficient to guarantee efficient performance, since poorly optimized queries can create a bottleneck in the system. Hence, each release of Hive has included new features for its optimizer aimed to generate better plans and deliver improvements to query execution. In this talk, we present the development of the optimizer since its initial release. We describe its current state and how Hive leverages the latest Apache Calcite features to generate the most efficient execution plans. We show numbers demonstrating the improvements brought to Hive performance, and we discuss future directions for the next-generation Hive optimizer, which include an enhanced cost model, materialized views support, and complex query decorrelation.
Geographica: A Benchmark for Geospatial RDF StoresKostis Kyzirakos
Geospatial extensions of SPARQL like GeoSPARQL and stSPARQL have recently been defined and corresponding geospatial RDF stores have been implemented. However, there is no widely used benchmark for evaluating geospatial RDF stores which takes into account recent advances to the state of the art in this area. In this paper, we develop a benchmark, called Geographica, which uses both real-world and synthetic data to test the offered functionality and the performance of some prominent geospatial RDF stores.

Apache Tez - Accelerating Hadoop Data Processinghitesh1892
Apache Tez - A New Chapter in Hadoop Data Processing. Talk at Hadoop Summit, San Jose. 2014 By Bikas Saha and Hitesh Shah.
Apache Tez is a modern data processing engine designed for YARN on Hadoop 2. Tez aims to provide high performance and efficiency out of the box, across the spectrum of low latency queries and heavy-weight batch processing.
Tez is the next generation Hadoop Query Processing framework written on top of YARN. Computation topologies in higher level languages like Pig/Hive can be naturally expressed in the new graph dataflow model exposed by Tez. Multi-stage queries can be expressed as a single Tez job resulting in lower latency for short queries and improved throughput for large scale queries. MapReduce has been the workhorse for Hadoop but its monolithic structure had made innovation slower. YARN separates resource management from application logic and thus enables the creation of Tez, a more flexible and generic new framework for data processing for the benefit of the entire Hadoop query ecosystem.
Everything you wanted to know about Apache Tez:
-- Distributed execution framework targeted towards data-processing applications.
-- Based on expressing a computation as a dataflow graph.
-- Highly customizable to meet a broad spectrum of use cases.
-- Built on top of YARN – the resource management framework for Hadoop.
-- Open source Apache incubator project and Apache licensed.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
