Testing TLS/SSL secured elastic cluster

ES-Hive integration is not working on secured elastic cluster

The details are below

Elasticsearch 7.8.0 (basic license), Hive 1.2.1000.2.6.5.0-292
TLS/SSL secured cluster has been configured and tested successfully with curl command and java JEST client on RHEL

curl --cacert /path/to/http.crt -u estester:estester_pwd -XGET 'https://ip:port/_cat/nodes?v'
curl --cacert /path/to/http.crt -u estester:estester_pwd -XGET 'https://ip:port/_cat/indices/books?pretty'

Add jars

hive> ADD JAR hdfs://xxxxx/tmp/elasticsearch-hadoop-7.8.0.jar;
hive> ADD JAR .../commons-httpclient-3.0.1.jar;

Create table

hive> create external table if not exists db_name.tbl_name (
id string,
title string,
year string)
STORED BY 'org.elasticsearch.hadoop.hive.EsStorageHandler'

Table created successfully, select failed with the details below

hive> select * from db_name.tbl_name;
OK
Failed with exception java.io.IOException:org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Cannot detect ES version- this typically happens if network/elasticsearch cluster is not accessible or when targetting a WAN/Cloud instance without proper setting in 'es.nodes.wan.only'

Note: When setting and configuring elastic cluster, I generated the following certificate files:
elastic-certificates.p12, elastic-stack-ca.p12, http.p12, http.crt
These files reside also in hdfs:///xxxxx/tmp/

A few questions please:
Q1: which of the above mentioned certificate file should be used for es.net.ssl.keystore.location and es.net.ssl.truststore.location ?

Q2: what would be the correct value for es.net.ssl.keystore.type ?

Q3: is referencing directory like hdfs:///xxxxx_domain/tmp correct for es.net.ssl.keystore.location and es.net.ssl.truststore.location ?

Am I missing something in table's properties or elsewhere ?

Thanks in advance
