best way to solve this is load the data in different partition each time you load the data. (depending on the data you can put the data partitioned by date or data-hour combination frequency on which you load the data)
I am not sure how you are installing sqoop. If you are using yum on redhat, then you can trying doing yum update or you can use apt-get to update. In hive 0.8.0 there is an option to append to already existing data but in this case you will need to make sure that duplication of data does not happen. So partitioning the data is simplest and easiest way to go for now.
