1. A method, in a data processing system, for optimization of a map/reduce distributed file system by log data analysis, the method comprising: initiating, by a name node in the distributed file system, a log analysis map/reduce job on one or more connected data nodes via a map/reduce processing framework in the distributed the system; receiving, by the name node, result data resulting from the log analysis map/reduce job from the one or more connected data nodes via the map/reduce processing framework in the distributed file system; performing, by the name node, analysis on the received result data; generating, by the name node, an optimization plan for the one or more connected data nodes based on results of the analysis; and initiating, by the name node, the optimization plan on the one or more connected data nodes via the map/reduce processing framework in the distributed file system.
