I have stored my database passwords in Hadoop CredentialProvider.
Sqoop import from terminal is working fine, successfully fetching the password from CredentialProvider.
sqoop import
-Dhadoop.security.credential.provider.path=jceks://hdfs/user/vijay/myPassword.jceks
--table myTable -m 1 --target-dir /user/vijay/output --delete-target-dir --username vijay --password-alias db2-dev-password
But when I try to setup as a Sqoop job, it is unable to recognize the -Dhadoop.security.credential.provider.path argument.
sqoop job --create my-sqoop-job -- import --table myTable -m 1 --target-dir /user/vijay/output --delete-target-dir --username vijay -Dhadoop.security.credential.provider.path=jceks://hdfs/user/vijay/myPassword.jceks --password-alias
Following is the error message:
14/04/05 13:57:53 ERROR tool.BaseSqoopTool: Error parsing arguments for import:
14/04/05 13:57:53 ERROR tool.BaseSqoopTool: Unrecognized argument: -Dhadoop.security.credential.provider.path=jceks://hdfs/user/vijay/myPassword.jceks
14/04/05 13:57:53 ERROR tool.BaseSqoopTool: Unrecognized argument: --password-alias
14/04/05 13:57:53 ERROR tool.BaseSqoopTool: Unrecognized argument: db2-dev-password
I couldn't find any special instructions in Sqoop User Guide for configuring Hadoop credential API with Sqoop Job.
How to resolve this issue?
Re positioning the Sqoop parameters solve the problem.
sqoop job -Dhadoop.security.credential.provider.path=jceks://hdfs/user/vijay/myPassword.jceks --create my-sqoop-job -- import --table myTable -m 1 --target-dir /user/vijay/output --delete-target-dir --username vijay --password-alias myPasswordAlias
Place the Hadoop credential before the Sqoop job keyword.
Your Sqoop job command is not proper, i.e. --password-alias is incomplete.
Please execute below command in your Hadoop server
hadoop credential list -provider jceks://hdfs/user/vijay/myPassword.jceks
Add the output in below Sqoop job command
sqoop job --create my-sqoop-job -- import --table myTable -m 1 --target-dir /user/vijay/output --delete-target-dir --username vijay -Dhadoop.security.credential.provider.path=jceks://hdfs/user/vijay/myPassword.jceks --password-alias <<output of above command>>

I created a hive internal table using sqoop command.
sqoop import -Dmapreduce.map.memory.mb=4096
--driver com.mysql.jdbc.Driver
--connect 'jdbc:mysql://{mysql_url}'
--username 'xxxx'
--password 'xxxx'
--input-fields-terminated-by '\t'
--split-by id
--target-dir {hdfs_path}
--verbose -m 1
--hive-drop-import-delims
--fields-terminated-by '\t'
--hive-import
--hive-table '{table_name}'
--query "select id from temp WHERE \$CONDITIONS LIMIT 10"
I created a table into it and it was working find.

I already hive-site.xml into sqoop conf directory.
cp ${HIVE_HOME}/conf/hive-site.xml ${SQOOP_HOME}/conf/hive-site.xml
"hive.metastore.uris" was set local and remote thrift.
How do I do? Help me. Thanks
Please used this sqoop command to import data from sqoop to hive with existing table and change clause according to your requirement.i have just modified some clause and added some clause as per requirement in your command
ubuntu#localhost:/usr/local/hive$ sqoop import -Dmapreduce.map.memory.mb=4096 --connect 'jdbc:mysql://localhost/test' --username 'root' -P --input-fields-terminated-by ',' --split-by id --target-dir /user/hive/warehouse/test_hive --hive-drop-import-delims --fields-terminated-by ',' --hive-import --hive-database default --hive-table test_hive --query "select id from test WHERE \$CONDITIONS LIMIT 10" --driver com.mysql.jdbc.Driver --delete-target-dir

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

Export requires an --export-dir argument or --hcatalog-table argument.
Try --help for usage instructions.
Could someone guide me on this. Thanks
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.
https://issues.apache.org/jira/browse/SQOOP-1270
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"
I am running below command to import data from Oracle Db to HIVE
sqoop import --connect jdbc:oracle:thin:#//localhost:1521/newDB --username <USERNAME> --P --table <ORACLE_TABLE_NAME> --hive-table <HIVE_TABLE_NAME> --hive-import -m 1

I find you are not used --create-hive-table and few other parameter in your query.
Below is the sqoop import query i use in my project:
oracle_connection.txt will have the connection info.
sqoop --options-file oracle_connection.txt \
--table $DATABASE.$TABLENAME \

From the error, I can guess that the output file is already in your target directory, may be from your previous sqoop import. There is an option in sqoop import named --delete-target-dir which will delete your target output directory and re-create them in your next sqoop import. Hope that helps.
I am getting the following error while trying to import table from MySql to HDFS. I am using cloudera CDH 4 VM.
