Importing configuration from local files

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.

Hadoop Configuration Import Wizard dialog box.

From this wizard, proceed as follows:

Procedure

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 wizard.
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 wizard.
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.
