> I'd like to use Hive to generate HFiles for HBase. I started off by following the instructions
on the [wiki|https://cwiki.apache.org/Hive/hbasebulkload.html], but that took me only so far.
TotalOrderPartitioning didn't work. That took me to this [post|http://stackoverflow.com/questions/13715044/hive-cluster-by-vs-order-by-vs-sort-by]
which points out that Hive partitions on value instead of key. A patched TOP brings me to
this error:
