In the past few years Amadeus has decided to rely on Big data platforms to develop advanced analytics modules and help airlines to improve their monitoring on performance insights. Big data platforms have matured since the introduction of Hadoop more than 10 years ago. Today Apache Spark represents the next-generation of data processing frameworks, providing ad- vanced in-memory capabilities and a directed acyclic graph (DAG) engine. Spark was developed to address the limitation of MapReduce, being 10–100 times faster in most of the data processing workloads. Nevertheless, Spark presents cases of application failures which are very difficult to interpret and, therefore, correct.
