Configuring the Components Catalog server

Procedure

Open the <Components_Catalog_Path>/config/application.properties file.
To change the default port exposed for the Components Catalog endpoints, edit the following line:
server.port=8989
To change the context path for the Components Catalog endpoints, edit the following line:
server.contextPath=/tcomp

Note that the server.contextpath and server.port properties must match the properties defined for tcomp.server.url in the <Data_Preparation_Path>/config/application.properties file.
To enable the Components Catalog server for use with Talend Data Preparation in a Big Data context, add the following line to the file:
hadoop.conf.dir=/path/to/Hadoop/configuration/directory

This property can also be set as an environment variable. Environment variables take precedence over values set in the application.properties file.
To use the Components Catalog server with a secure Hadoop cluster (using Kerberos), add the following line to the file:
krb5.config=/path/to/Kerberos/configuration/file/krb5.conf

This property can also be set as an environment variable. Environment variables take precedence over values set in the application.properties file.
Save your changes to the properties file.
Restart Components Catalog for your changes to be taken into account. You can do so using the start.sh script in the <Components_Catalog_Path> folder.
