Sqoop export from hdfs to GreenPlum is not working - hadoop

Question

I am trying to export data from hdfs location to Greenplum user defined schema (not default schema).
Tried Sqoop Eval to check the connection.
sqoop eval --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sample_user --password xxxx --query "SELECT * FROM sample_db.sample_table LIMIT 3"
Result:
working fine
Tried with --schema option
/usr/bin/sqoop export --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sampleuser --password samplepassword --table sample_table --schema sample_schema --export-dir=/sample/gp_export --input-fields-terminated-by ',' --update-mode allowinsert
Result:

Added extra '--' before '--schema' based on the sqoop documentation
https://sqoop.apache.org/docs/1.4.3/SqoopUserGuide.html
/usr/bin/sqoop export --connect "jdbc:postgresql://sample.com:5432/sampledb" --username sampleuser --password samplepassword --table sample_table -- --schema sample_schema --export-dir=/sample/gp_export --input-fields-terminated-by ',' --update-mode allowinsert

Export requires an --export-dir argument or --hcatalog-table argument.
Try --help for usage instructions.
Could someone guide me on this. Thanks

Answer 1

Thanks to #cricket_007 for clarification.
--schema argument should be last in the sqoop command. So below code is working.
/usr/bin/sqoop export --connect "jdbc:postgresql://sample.com:5432/sampledb" \
--username sampleuser --password samplepassword \
--export-dir=/sample/gp_export --input-fields-terminated-by ',' \
--table sample_table -- --schema sample_schema
But UPSERT operations not supported in postgresSql. There is an open Jira ticket here.

After the --export-dir you don't need the = check out the example below. Another suggestion is to use --verbose when you run into these kinds of issues.
sqoop export --libjars /path/some.jar \
--connect 'jdbc:sqlserver://IP:1433;database=db' \
--username someName -password somePassword -m 10 \
--verbose --mysql-delimiters \
--export-dir /HDFS/Path/someFile.csv \
--table "RDBMSTABLENAME"
