Hi,
We 've been using hadoop 15.5 in our production environment where we have about
10 TB of data stored on the dfs.
The files were generated as mapreduce output. We want to move our env. to
Amazon Elastic Map Reduce (EMR) which throws the following questions to us:
1. EMR supports only hadoop 19.0 and above. Is it possible to use the current
data that were generated with hadoop 15.5 from hadoop 19.0?
2. Or how can we make it possible to use or update to hadoop 19.0 from hadoop
15.5? What are the issues expected while doing so?
Regards,
Ilayaraja
