----------------------------------
Summary: Total ordering of Hive output
Key: HIVE-4627
URL: https://issues.apache.org/jira/browse/HIVE-4627
Project: Hive
Issue Type: Bug
Affects Versions: 0.11.0
Reporter: Nick Dimiduk
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:
