hi, folks, I am using the HBaseintergration feature from hive ( https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration) to load TPCH tables into HBase. Hive 0.13 and HBase 0.98.6.
The load works well. However, as documented here: https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration#HBaseIntegration-KeyUniqueness. The key uniqueness prevents me from loading all 'lineitem' rows. As 'lineitem' table is using "L_ORDERKEY, L_LINENUMBER" as compound primary key. If I only mapped to 'L_ORDERKEY" as hbase key(aka, row #). Many rows will get overwritten. Any suggestion? someone on this list must go through this already. :-). Thanks BTW, here is my hive ddl. create table hbase_lineitem( *l_orderkey bigint*, l_partkey bigint, l_suppkey int, l_linenumber bigint, l_quantity double, l_extendedprice double, l_discount double, l_tax double, l_returnflag string, l_linestatus string, l_shipdate string, l_commitdate string, l_receiptdate string, l_shipinstruct string, l_shipmode string, l_comment string ) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping"* = ":key*,l_partkey:val,l_suppkey:val, l_linenumber:val, l_quantity:val, l_extendedprice:val, l_discount:val, l_tax:val, l_returnflag:val, l_linestatus:val, l_shipdate:val, l_commitdate:val, l_receiptdate:val, l_shipinstruct:val, l_shipmode:val, l_comment:val ") TBLPROPERTIES ("hbase.table.name" = "lineitem"); insert overwrite table hbase_lineitem select * from lineitem; Demai
