When I built the es cluster, I used bin/elasticsearch-certutil to generate the CA certificate and p12 certificate, but I did not enter the password, but chose to press Enter directly.
When I want to use spark to connect to es, I find that he needs my es.net.ssl.keystore.pass, I set it to an empty string, but an error is reported. So I'm wondering if there is a default value, or how much I should enter
Hello. The es I use is version 8.5.3, and the certificate is automatically generated at startup. Here is my configuration:
properties.put("es.net.ssl", "true");
properties.put("es.net.ssl.keystore.location", "file:/mypath/conf/http.p12");
properties.put("es.net.ssl.keystore.pass", "");
properties.put("es.net.ssl.keystore.type", "PKCS12");
This is the error stack displayed by spark：
Exception in thread "main" org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Cannot detect ES version - typically this happens if the network/Elasticsearch cluster is not accessible or when targeting a WAN/Cloud instance without the proper setting 'es.nodes.wan.only'

Looks like the password cannot be null
Yes the password can't be null so I would recommend setting up a password and checking your settings.
