Abstract: Different types of event data generated by a computing platform are transformed in parallel by a group of reducers during a reduce phase of a single map-reduce job into a set of different computed outputs that impose different types of storage formats based upon differing data characteristics of the respective different computed outputs. The set of different computed outputs are written to storage in parallel by the group of reducers during the reduce phase of the single map-reduce job according to the imposed different types of storage formats.

Abstract: A wireless emergency lighting system for a structural object such as a transportation vehicle. The system includes a multiplicity of discrete wireless emergency lighting assemblies installed in the transportation vehicle at spaced apart locations for assisting passengers of the transportation vehicle to exit the transportation vehicle in an emergency situation. Each emergency lighting assembly has an emergency lighting component, a micro processor for controlling the operations of the emergency lighting component, a memory device for storing information of the emergency lighting component, a battery for providing electrical power to the emergency lighting component, and means for receiving and transmitting radio signals. The system also includes at least one control module for wireless interrogation of the multiplicity of discrete wireless emergency lighting assemblies.
