Hi All,
I am having issue hive LEFT OUTER JOIN. I had al table in sql-server. then used sqoop to migrate all tables on hive. This is the original query from sql-server which contains non-equi LEFT OUTER JOIN. both table have *cartesian data*. SELECT vss.company_id,vss.shares_ship_id,vss.seatmap_cd,vss.cabin,vss.seat, vss.seat_loc_dscr, vss.ep_seat AS EPlus_Seat, vss.ep_win_seat, vss.ep_asle_seat, vss.ep_mid_seat, vss.em_win_seat, vss.em_mid_seat,vss.em_asle_seat,vss.y_win_seat, vss.y_mid_seat, vss.y_asle_seat, vss.fj_win_seat, vss.fj_mid_seat, vss.fj_asle_seat,vss.exit_row, vss.bulkhead_row, vss.eff_dt, vss.disc_dt FROM rvsed11 zz LEFT OUTER JOIN rvsed22 vss ON zz.company_id = vss.company_id AND zz.shares_ship_id = vss.shares_ship_id AND *zz.report_dt >= vss.eff_dt * AND *zz.report_dt < vss.disc_dt*; As we know that Nonequi joins are not working in hive ( Nonequi joins working in WHERE clause but we cannot use with LEFT OUTER JOIN). See below hive query with noon-equi condition moved to where clause. SELECT vss.company_id,vss.shares_ship_id,vss.seatmap_cd,vss.cabin,vss.seat, vss.seat_loc_dscr, vss.ep_seat AS EPlus_Seat, vss.ep_win_seat, vss.ep_asle_seat, vss.ep_mid_seat, vss.em_win_seat, vss.em_mid_seat,vss.em_asle_seat,vss.y_win_seat, vss.y_mid_seat, vss.y_asle_seat, vss.fj_win_seat, vss.fj_mid_seat, vss.fj_asle_seat,vss.exit_row, vss.bulkhead_row, vss.eff_dt, vss.disc_dt FROM rvsed11 zz LEFT OUTER JOIN rvsed22 vss ON zz.company_id = vss.company_id AND zz.shares_ship_id = vss.shares_ship_id *WHERE zz.report_dt >= vss.eff_dt AND zz.report_dt < vss.disc_dt;* Original query is giving 1162 records on Sql-Server , but this hive query giving 46240 records. I tried multiple workaround to get same logic , but didn't get same result on hive. Can you please help me on this to identify this issue and get query working on hive with same result set. Let me know you need other details. Regards Sanjiv Singh Mob : +091 9990-447-339
