How to specify Trust store and trust store type for Spark JDBC connection

问题

I am new to Spark and we are currently using the spark-java to create orc files from Oracle database. I was able to configure the connection with

sqlContext.read().jdbc(url,table,props)

However, I couldn't find any way in the properties to specify the trustStore or trustStoreType. Can someone help me about how to specify these properties?

I already tried populating the properties as

 props.put("trustStore", "<PATH_TO_SSO>");
 props.put("trustStoreType", "sso");

But it didn't work for me

Update1: I have tried what user8371915 has suggested and also placed the sso file in both my executor nodes. I am still getting the following exception (abridged version)

回答1:

First of all (credits go to Xephi for this answer) properties are javax.net.ssl.trustStore and javax.net.ssl.trustStoreType.

The second problem is that trustStore should be accessible on each executor node. Being able to access it from the driver is not enought.
