PARALLEL write data is wrong.

[killerwzb]

hi

 I use benchmarksql generate data and Consistency checking，but i find one problem if i use this opition "WRITE=PARALLEL ", the result is wrong. Can you help me ?
The following is my steps:

1. use benchmarksql generate 1000 warehouse data。

**cat 1000.pg**

db=postgres
driver=org.postgresql.Driver
conn=jdbc:postgresql://localhost/benchmarksql?
socketFactory=org.newsclub.net.unix.AFUNIXSocketFactory$FactoryArg&socketFactoryArg=/tmp/.s.PGSQL.5667
user=benchmarksql
password=123456

warehouses=200
loadWorkers=64

terminals=800
//To run specified transactions per terminal- runMins must equal zero
runTxnsPerTerminal=0
//To run for specified minutes- runTxnsPerTerminal must equal zero
runMins=30
//Number of total transactions per minute
limitTxnsPerMin=0

//Set to true to run in 4.x compatible mode. Set to false to use the
//entire configured database evenly.
terminalWarehouseFixed=true

//The following five values must add up to 100
//The default percentages of 45, 43, 4, 4 & 4 match the TPC-C spec
newOrderWeight=45
paymentWeight=43
orderStatusWeight=4
deliveryWeight=4
stockLevelWeight=4

// Directory name to create for collecting detailed result data.
// Comment this out to suppress.
/resultDirectory=my_result_%tY-%tm-%td_%tH%tM%tS
//osCollectorScript=./misc/os_collector_linux.py
//osCollectorInterval=1
//osCollectorSSHAddr=user@dbhost
//osCollectorDevices=net_enp0s3 blk_sda

I use this command get some csv file in this path:
./runLoader.sh 1000.pg fileLocation /home/nbase/data/testdata/

2、load data into database

pg_bulkload -i /home/wzb/testdata/order.csv -O bmsql_oorder -l bmsql_oorder-bulkload.log -P bmsql_oorder-bad.log -o "TYPE=CSV" -o "NULL=NULL" -o "WRITER=PARALLEL" -d benchmarksql -U postgres -p 5667
pg_bulkload -i /home/wzb/testdata/order-line.csv -O bmsql_order_line -l bmsql_order_line-bulkload.log -P bmsql_order_line-bad.log -o "TYPE=CSV" -o "NULL=NULL" -o "WRITER=PARALLEL" -d benchmarksql -U postgres -p 5667

3、Consistency checking

(select o_w_id, o_d_id, sum(o_ol_cnt) from bmsql_oorder group by o_w_id, o_d_id) except (select ol_w_id, ol_d_id, count
(ol_o_id) from bmsql_order_line group by ol_w_id, ol_d_id);

If this result is 0 rows,then it is right. but i get some rows .

4、if I change the "WRITER=PARALLEL" to "WRITER=DIRECT", i can get 0 rows.
