Hi, I have two logs which should have all the records for the same record_id, in other words, if this record_id is found in the first log, it should also be found in the second one. However, I suspect that the second log is filtered out, and I need to find the missing records. Anything is allowed: MapReduce job, Hive, Pig, and even a NoSQL database.
Thank you. It is also a good time to express my thanks to all the members of the group who are always very helpful. Sincerely, Mark
