hi, folks,

I am= using the HBaseintergration feature from hive (https://cwiki.apache.org= /confluence/display/Hive/HBaseIntegration) to load TPCH tables into HBa= se. Hive 0.13 and HBase 0.98.6.

The load works well. Ho= wever, as documented here: https://cwiki.= apache.org/confluence/display/Hive/HBaseIntegration#HBaseIntegration-KeyUni= queness.

The key uniqueness prevents me from loading all = 'lineitem' rows. As 'lineitem' table is using "L_ORDER= KEY, L_LINENUMBER" as compound primary key. If I only mapped to 'L= _ORDERKEY" as hbase key(aka, row #). Many rows will get overwritten. <= br>
Any suggestion? someone on this list must go through this alre= ady. :-). Thanks

BTW, here is my hive ddl.
