Hi Shi Wei,
looks like you're the first trying to connect to ES from Nutch over
HTTPS. HTTP is used as default scheme and there is no way to configure
the Elasticsearch index writer to use HTTPS.
Please open a Jira issue. It's a trivial fix.
For a quick fix: in the Nutch source package (or git tree) edit the file
src/plugin/indexer-elastic/src/java/org/apache/nutch/indexwriter/elastic/ElasticIndexWriter.java
and change the line
hostsList[i++] = new HttpHost(host, port);
into
hostsList[i++] = new HttpHost(host, port, "https");
After that you need to build nutch by running
ant runtime
See
https://www.javadoc.io/static/org.apache.httpcomponents/httpcore/4.3.2/org/apache/http/HttpHost.html#HttpHost(java.lang.String,%20int,%20java.lang.String)
Best,
Sebastian
