my Component Version  
ES 5.4.3  
ES-hadoop 5.4.3  
SearchGuard 5.4.3  
in [es-hadoop-security](https://www.elastic.co/guide/en/elasticsearch/hadoop/5.0/security.html) Only supported Username/Password or PKI/X.509 ，I don't know how to configure the path of the pem and key files.  
Just like the following code is implemented in es-hadoop：

Settings settings = Settings.builder() .put(SSLConfigConstants.SEARCHGUARD\_SSL\_TRANSPORT\_PEMKEY\_FILEPATH,"/home/lixiang/tzq/clinet1.key") .put(SSLConfigConstants.SEARCHGUARD\_SSL\_TRANSPORT\_PEMCERT\_FILEPATH,"/home/lixiang/tzq/clinet1.pem") .put(SSLConfigConstants.SEARCHGUARD\_SSL\_TRANSPORT\_PEMTRUSTEDCAS\_FILEPATH, "/home/lixiang/tzq/root-ca.pem") .put(SSLConfigConstants.SEARCHGUARD\_SSL\_TRANSPORT\_PEMKEY\_PASSWORD, "nit6hwlmtNIL") .put(SSLConfigConstants.SEARCHGUARD\_SSL\_TRANSPORT\_ENFORCE\_HOSTNAME\_VERIFICATION, false) .put("client.transport.sniff",false) .put("cluster.name","my-es" ).build();  
Please help me！
