Strata + Hadoop World New York 2015 needs your developer demos! The proposal period closes on Aug. 14.
As everyone knows, Apache Hadoop’s overwhelming success is partly premised on de-centralized innovation from all corners of the community—users, vendors, and academia—with everyone participating on a level playing field. And since 2011, Strata + Hadoop World has been a community and content hub of that ecosystem.
For the 2015 show in New York (Sept.
The Strata + Hadoop World NYC 2015 (Sept. 29-Oct. 3) agenda was published in the last few days. Congratulations to all accepted presenters!
In this post, I just want to provide a concise digest of the tutorials and sessions that will involve Cloudera or Intel engineers and/or interesting use cases. There are many worthy sessions from which to choose, so we hope this list will influence your decisions about where to spend your time during the week!

Salted Apache HBase tables with pre-split is a proven effective HBase solution to provide uniform workload distribution across RegionServers and prevent hot spots during bulk writes. In this design, a row key is made with a logical key plus salt at the beginning. One way of generating salt is by calculating n (number of regions) modulo on the hash code of the logical row key (date,
Evaluating which streaming architectural pattern is the best match to your use case is a precondition for a successful production deployment.
The Apache Hadoop ecosystem has become a preferred platform for enterprises seeking to process and understand large-scale data in real time. Technologies like Apache Kafka, Apache Flume, Apache Spark, Apache Storm, and Apache Samza are increasingly pushing the envelope on what is possible. It is often tempting to bucket large-scale streaming use cases together but in reality they tend to break down into a few different architectural patterns,
Your contributions, and a vibrant developer community, are important for Impala’s users. Read below to learn how to get involved.
From the moment that Cloudera announced it at Strata New York in 2012, Impala has been an 100% Apache-licensed open source project. All of Impala’s source code is available on GitHub—where nearly 500 users have forked the project for their own use—and we follow the same model as every other platform project at Cloudera: code changes are committed “upstream”
