                 URL: https://issues.apache.org/jira/browse/NUTCH-2906

See [discussion on user@nutch|https://lists.apache.org/thread/tlj077ssc6v75pn7w59d6szcr9z6xh0z]: passwords and credentials need to be stored in the index-writers.xml in plain text. It should be possible to use a credential provider or other options to hide these sensitive strings, cf.
