Create a keytab for the user "kuser1". You can use the
kadmin.local command line interface to add principals and
create keytab files, as shown shown below.
Retrieve the keytab file into the client machine. Use TalendtSCPGet component or retrieve it manually with the UNIX
cp command.
In this example, cp command is used to move the keytab
file to the UNIX home directory of the "kuser1" user where it has the read
access to the keytab file.
In the Integration perspective of the Talend Studio, create an
empty Job.

Component view.
In the Version area, select the distribution to be
connected to.
In this scenario, it is Cloudera from the
Distribution list and Cloudera CDH5.4 from the
Hadoop version list.
In the NameNode URI field, enter the location of the
NameNode. If you are using WebHDFS, the location should be

supported yet.
In this example, it is
hdfs://quickstart.cloudera:8020.
Select Use Kerberos authentication and enter
nn/_HOST@EXAMPLE.COM in the NameNode
principal field.
Information noteTip: You can find the NameNode principal value in the
hdfs-site.xml file of the cluster you are
using.
Select the Use a keytab to authenticate check box.
In the Principal field, enter the principal name of the
keytab file.
It is kuser1 in this example.
