dear juanjo, these are great news which for me are clarifing very well the situation :-) however, please bear in mind that the documentation in the catalogue is not up-to-date and that several smes are wishing to install it (wrong or correct this does not matter too much) and following the current installation guidelines the installation does not work as reported in several emails from smes. ciao, stefano 2015-07-22 15:24 GMT+02:00 Juanjo Hierro <juanjose.hierro at telefonica.com>: > Hi, > > (Please replace my previous mail with this one, more complete (I > accidentally click on send too early :-) > > We don't understand how this message about Telefónica discontinuing > support of Cosmos has been disseminated. Let me clarify: > > - Cosmos continues being the product that Telefónica supports as > implementation of the Big Data enabler.

Reasons for this > change are several, but the most important ones are: > - Sahara natively integrates with Openstack, the virtualization > infrastructure used in FIWARE, therefore the "Hadoop as a Service" engine > would be much better integrated with OpenStack-based clouds like the FIWARE > Lab. Based on DevStack, we will be also available to support this "Hadoop > as a Service" functionality standalone (without requiring to deploy and > setup a complete Cloud) on a number of dedicated servers. > - Sahara offers at least the same functionality offered by the > initial software to support "Hadoop as a Service" functionality developed > by Telefónica.

As part of our support, > Telefónica is recommending these SMEs/startups who don't require a "Hadoop > as a Service" functionality to go for any of the following two options: > - To use the shared Hadoop cluster available at FIWARE Lab. This > global instance has no 24x7 support nor production-like SLAs as it happens > with the rest of the FIWARE Lab service. However, Telefónica's team is > committed to provide its best to support in time, whenever issues are > reported. We believe that the performance for this support is good. > - If the above is not enough and you are looking for a production > environment, then you will need to install Hadoop in your own > infrastructure by using any of the available distributions. In this > case, Telefónica is ready to support users on installing Hadoop as well. > - Replacing the "Hadoop as a Service" engine doesn't affect at all how > applications performing map-reduce bigdata analysis is performed with > Cosmos.
