SQLSyntaxErrorException on sqoop export when table column has space

Inline with SQOOP-468, if a column name of table has a space in it, the sqoop export fails with ORA-00904.
During debugging this becomes clear, preferred if either exception handling or messaging can be improved.

Sqoop: 1.4.3 (cdh 4.3.1)
command: sqoop export Dmapred.job.queue.name=<queue_name>-connect <connection> --username <username> --password <password> --table <table> --input-fields-terminated-by "|" --input-lines-terminated-by
n --export-dir <export_dir> --input-null-string '
N' --input-null-non-string 'N'

error:
java.io.IOException: java.sql.SQLSyntaxErrorException: ORA-00904: "COL_E": invalid identifier
