About this task
Once you have selected Import configuration from local files in the import wizard, the following wizard is opened to help you select the Hadoop configuration files (mainly the *-site.xml files) to be used from the local machine.
From this wizard, proceed as follows:
Click Browse... to access the folder in
which the local configuration files to be used are stored and click
OK to list the configurations in this
It is recommended to store these configuration files using a short access path in the local machine.The following image shows some files used for the configuration of HDFS and Yarn in Cloudera. These sample files are downloaded and automatically generated by Cloudera manager.
From the configuration list, select the configurations to be
imported, for example, those for HDFS,
and click Finish.
Then the relevant configuration information is automatically filled in the next step of the Hadoop cluster connection wizard.
- In this Hadoop cluster connection wizard, verify the Use custom Hadoop configurations check box is selected to ensure that the entire configuration you have imported is taken into account. If you clear this check box, Talend Studio uses its default Hadoop configuration (in the form of a jar file) instead to complement the parameters you have explicitly set in this wizard.
Click the Check services button to verify that Talend Studio can
connect to the NameNode and the ResourceManager services you have specified in this
A dialog box pops up to indicate the checking process and the connection status. If it shows that the connection fails, you need to review and update the connection information you have defined in the connection wizard.
- Click Finish to validate the changes.
