The export tool exports a set of files from HDFS back to an RDBMS. The target table must already exist in the database. The input files are read and parsed into a set of records according to the user-specified delimiters.
Example :
sqoop export \
--connect="jdbc:<databaseconnector>" \
--username=<username> \
--password=<password> \
--export-dir=<hdfs export directory> \
--table=<tablename>
