Re: Reflect MySQL updates into Hive
Hello Ibrahim,

     A quick questio. Are you planning to replace your SQL DB with Hive? If
that is the case, I would not suggest to do that. Both are meant for
entirely different purposes. Hive is for batch processing and not for real
time system. So if you are requirements involve real time things, you need
to think before moving ahead.

Yes, Sqoop is 'the' tool. It is primarily meant for this purpose.


Best Regards,
