Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "Hbase/PoweredBy" page has been changed by stack: http://wiki.apache.org/hadoop/Hbase/PoweredBy?action=diff&rev1=75&rev2=76 [[http://www.openplaces.org|Openplaces]] is a search engine for travel that uses HBase to store terabytes of web pages and travel-related entity records (countries, cities, hotels, etc.). We have dozens of MapReduce jobs that crunch data on a daily basis. We use a 20-node cluster for development, a 40-node cluster for offline production processing and an EC2 cluster for the live web site. - [[http://www.powerset.com/|Powerset (a Microsoft company)]] uses HBase to store raw documents. We have a ~110 node hadoop cluster running DFS, mapreduce, and hbase. In our wikipedia hbase table, we have one row for each wikipedia page (~2.5M pages and climbing). We use this as input to our indexing jobs, which are run in hadoop mapreduce. Uploading the entire wikipedia dump to our cluster takes a couple hours. Scanning the table inside mapreduce is very fast -- the latency is in the noise compared to everything else we do. + [[http://www.pnl.gov|Pacific Northwest National Laboratory]] - Hadoop and HBase (Cloudera distribution) are being used within PNNL's Computational Biology & Bioinformatics Group for a systems biology data warehouse project that integrates high throughput proteomics and transcriptomics data sets coming from instruments in the Environmental Molecular Sciences Laboratory, a US Department of Energy national user facility located at PNNL. The data sets are being merged and annotated with other public genomics information in the data warehouse environment, with Hadoop analysis programs operating on the annotated data in the HBase tables. This work is hosted by olympus, a large PNNL institutional computing cluster (http://www.pnl.gov/news/release.aspx?id=908) , with the HBase tables being stored in olympus's Lustre file system. [[http://www.readpath.com/|ReadPath]] uses HBase to store several hundred million RSS items and dictionary for its RSS newsreader. Readpath is currently running on an 8 node cluster.
