Hi Dean, Actually I was having Hadoop and Hive cluster on EMR and I have S3 storage containing logs which updates daily and having partition with date(dt). And I was using this recover partition. Now I wanted to shift to EC2 and have my own Hadoop and Hive cluster. So, what is the alternate of using recover partition in this case, if you have any idea ? I found one way of individually partitioning all dates, so I have to write script for that to do so for all dates. Is there any easiest way other than this ?
