HDInsight Hadoop Cluster is not Responding Issue
This is a quick post to describe a solution to a problem I was having with my local installation of the HDInsight Hadoop cluster.

Architectures for Running SQL Server Analysis Service (SSAS) on Data in Hadoop Hive
Recently I have been involved in researching and building a low-latency high-data-volume OLAP environment for a social entity and interaction analysis platform, the perfect mixture of concepts such as Big Data collection and processing, large-scale Network Analysis, Natural Language Processing (NLP) and a highly scaled-out OLAP environment for end users to explore and discover data (essentially a Self-Service and Exploratory BI layer).
It is by all means not an easy mission to orchestrate all the technologies that back those concepts, particularly if you are interested in using the optimum solution for the problem at hand, for example Big Data might be better handled by a Hadoop layer, but Hadoop or Hive (at least on their own) are not geared up to respond to OLAP queries, which are real-time by nature, and even if they were, your end-user needs familiar tools and interfaces to analyse and study this data, which is where SQL Server Analysis Service and the whole Microsoft BI stack might come in and offer great integration with already existing business applications (such as Office or SharePoint).
This post discusses a few architectural approaches to exposing a Hadoop layer through a SQL Server Analysis Service (SSAS) interface, with references to data-latency, redundancy and over-all performance.
Microsoft Big Data: Hadoop through HDInsight Server
After a year from announcing partnership and starting the collaboration project, Microsoft (SQL Server) and Hortonworks (Hadoop) have finally announced the result of this integration: Microsoft HDInsight Server and HDInsight Azure Service.
So what is HDInsight? well, it is essentially Microsoft’s Hadoop-based distribution which is built on top of the Hortonworks Data Platform. So if you download Microsoft HDInsight Server for a local installation of the Hadoop distribution, then you will end up with a local cluster with your own Hadoop Hive able to run Hadoop jobs, as well as benefit from the already released Hadoop integration points with SharePoint and EXCEL. This is just so powerful!
