Hi Shi Wei, for the nutch-site.xml it's possible to use Java properties and/or environment variables, see section "Variable expansion" in
https://hadoop.apache.org/docs/r3.3.1/api/org/apache/hadoop/conf/Configuration.html In case you're asking about index-writers.xml - variable expansion (likely) does not work. Note: I didn't try it. But it's a scheme specific to Nutch and not a Hadoop configuration file and I cannot remember that any expansion mechanism is implemented when the index-writers.xml is read. Anyway, the better way would be to rely primarily on a credential provider, see https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/CredentialProviderAPI.html https://hadoop.apache.org/docs/stable/api/org/apache/hadoop/conf/Configuration.html#getPassword-java.lang.String- If you have time, please open a Jira issue (or multiple ones) to get a more safe way to hold credentials implemented.
