Ambari Blueprint allows an operator to instantiate a Hadoop cluster quickly—and reuse the blueprint to replicate cluster instances elsewhere, for example, as development and test clusters, staging clusters, performance testing clusters, or co-located clusters.
Ambari now extends database support for Ambari DB, Hive and Oozie to include PostgreSQL. This means that Ambari now provides support for the key databases used in enterprises today: PostgreSQL, MySQL and Oracle. The PostgreSQL configuration choice is reflected in this database support matrix.
AWS has been working with the NASA Earth Exchange (NEX) team to make it easier and more efficient for researchers to access and process earth science data. The goal is to make a number of important data sets accessible to a wider audience of full-time researchers, students, and citizen scientists. This important new project is called OpenNEX. Up until now, it has been logistically difficult for researchers to gain easy access to this data due to its dynamic nature and immense size (tens of terabytes). Limitations on download bandwidth, local storage, and on-premises processing power made in-house processing impractical.
Access Dataset: s3://nasanex/NEX-DCP30
The NASA Earth Exchange (NEX) Downscaled Climate Projections (NEX-DCP30) dataset is comprised of downscaled climate scenarios for the conterminous United States that are derived from the General Circulation Model (GCM) runs conducted under the Coupled Model Intercomparison Project Phase 5 (CMIP5) [Taylor et al. 2012] and across the four greenhouse gas emissions scenarios known as Representative Concentration Pathways (RCPs) [Meinshausen et al. 2011] developed for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). The dataset includes downscaled projections from 33 models, as well as ensemble statistics calculated for each RCP from all model runs available. The purpose of these datasets is to provide a set of high resolution, bias-corrected climate change projections that can be used to evaluate climate change impacts on processes that are sensitive to finer-scale climate gradients and the effects of local topography on climate conditions.
Each of the climate projections includes monthly averaged maximum temperature, minimum temperature, and precipitation for the periods from 1950 through 2005 (Retrospective Run) and from 2006 to 2099 (Prospective Run).
