Sqoop import for Netezza connector in direct mode hangs

PROBLEM

Running sqoop import command in direct mode for accessing a Netezza data warehouse appliance hangs at 100% map

sqoop import --options-file sqoop_opts_file.opt
.

INFO mapreduce.Job: Running job: job_1465914632244_0005

The sqoop_opts_file.opt had the following options :

-connect
jdbc:netezza://xxxxxxxxxxxxxxxxxxxxxx:5480/
--username
XXXX
--password
***************
--direct
--direct-split-size
1000000
--compress
--table
table_name
--target-dir
/user/root/table_name
--verbose

Yarn logs show the below errors

org.netezza.error.NzSQLException: ERROR: found delim ',' in a data field, specify escapeChar '\' option in the external table definition
