How to use Kerberos Authentication in Sqoop?

How to use Kerberos Authentication in Sqoop?

New Contributor

I want to kerberize the sqoop job. What is the process? What are the things to be taken care to run the sqoop job in Kerberos environement? I didn't find any documentation on this. Your help is most important.

Kerberos is used for authentication, so you would follow the instructions for Kerberizing your cluster as found here:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_security/content/ch_hdp-security-guide-ov...

Once you create Principals for your users, they will be able to authenticate using Kerberos and run sqoop jobs.

This may help too:

https://cwiki.apache.org/confluence/display/SQOOP/Security+Guide+On+Sqoop+2

you need to create Principals for sqoop.

We are not using Sqoop2. Does the security guide applies to Sqoop too?

I have found a solution to this provided by another user here: https://community.hortonworks.com/questions/20719/sqoop-to-sql-server-with-integrated-security.html

Basically if you switch to the jtds driver which you can download here: http://jtds.sourceforge.net/

Sqoop SQL Server data import to HDFS worked with manual parametric the authentication(using windows credential) with added parameter on the SQL Server JDBC driver, as integrated security is not supported by the SQL driver as of now due to the Kerberos authentication(Delegated tokens distributed over cluster while running MR job).

So we need to pass the windows authentication with password and with the integrated security disabled mode to import the data to the system. As normal SQL server driver does not support, so I had used the jtds.jar and the different driver class to pull the data to the Hadoop Lake.

Sample Command I tried on the server as follows,

sqoop import --table Table1 --connect "jdbc:jtds:sqlserver://<Hostname>:<Port>;useNTLMv2=true;domain=<WindowsDomainName>;databaseName=XXXXXXXXXXXXX" \

--connection-manager org.apache.sqoop.manager.SQLServerManager --driver net.sourceforge.jtds.jdbc.Driver --username XXXXX --password 'XXXXXXX' \

--verbose --target-dir /tmp/33 -m 1 -- --schema dbo

"

Here are some examples that worked for me:

# List databases

sqoop list-databases --connect "jdbc:jtds:myactivedirectorydomain.com" --connection-manager org.apache.sqoop.manager.SQLServerManager --driver net.sourceforge.jtds.jdbc.Driver --username XXXXX -P

# List tables

sqoop list-tables --connect "jdbc:jtds:myactivedirectorydomain.com;databaseName=DATABASENAMEHERE" --connection-manager org.apache.sqoop.manager.SQLServerManager --driver net.sourceforge.jtds.jdbc.Driver --username jmiller.admin -P

# Pull data example

sqoop import --table TABLENAMEHERE --connect "jdbc:jtds:myactivedirectorydomain.com;databaseName=DATABASENAMEHERE" --connection-manager org.apache.sqoop.manager.SQLServerManager --driver net.sourceforge.jtds.jdbc.Driver --username XXXXX -P --fields-terminated-by '\001' --target-dir /user/XXXXX/20170313 -m 1 -- --schema dbo

Note* In the above example you need to change the username to your username and database name in the list-tables or pull to the one you need (note the AD account you use will require access to the data).

This article will help you to implement kerberos and add kerberos principal:
