Fellow BigTop'pers. We have just rolled out a readily available Spark 0.5 (www.spark-project.org) packaged for Ubuntu distribution. This package is build against current official Apache Hadoop 1.0.3, so it should be compatible with everything from 0.20.205 up to Hadoop 1.1 release candidate. Redhat/CentOS version is coming in a few days (in case someone is interested).
You can find all related information at http://www.magnatempusgroup.net/blog/2012/09/24/incredibly-fast-in-memory-analytics-for-bigdata-technology-preview/ and download installable package from http://magnatempusgroup.net/ftphost/releases/Spark-0.5-1.0.3/ I am posting this here, because the package is created in the exact standards of BigTop stack. In other words, BigTop rules! We would love to hear your feedback and comments! -- With regards, Alef MTG development team
