I don't know whether my usual error is related to this one but is very
similar and it happens randomly...I still have to figure out the root cause
of the error:
java.lang.Exception: The data preparation for task 'CHAIN GroupReduce
(GroupReduce at createResult(IndexMappingExecutor.java:43)) -> Map (Map at
main(Jsonizer.java:90))' , caused an error: Error obtaining the sorted
