Description

Hi, I am trying to export an AVRO data file from HDFS to Oracle database (11gR2) using an update-key in sqoop command Ex:
sqoop export \
--connect jdbc:oracle:thin:@X.X.X.X:1521/xe \
--username ***** \
--password ***** \
--table XXX \
--update-key <primary-key-column-name> \
--update-mode allowinsert \
--export-dir <hdfs-path>

However, the same export is successful without using the "update-key" in sqoop command.
