-------------------------------------------

There seems to be a lot of unnecessary changes in the patch [~thomastechs]. Are you planning to clean it up?

> To reproduce this error, execute the sqoop query connecting to DB2 with the option WITH UR and number of mappers > 1 and a split by column:
> {code:title=Sample query|borderStyle=solid}
> sqoop import --connect jdbc:db2://<host>/hadoopguide --username <uname> --password <password>  --query 'SELECT A_I,B_I,C_I,D_I FROM A where $CONDITIONS WITH UR' --split-by A_I -m 8 --target-dir /user/sample/test_with_ur;
> {code} 
> Then the sqoop log is printed like :
> {code:title=Sample query|borderStyle=solid}
> INFO db.DataDrivenDBInputFormat: BoundingValsQuery: SELECT MIN(A_I), MAX(A_I) FROM (SELECT A_I,B_I,C_I,D_I FROM A where  (1 = 1)  WITH UR) AS t1
