No suitable driver found for jdbc:hive2..

 The error in the log indicates that the JDBC driver for Hive (jdbc:hive2://) is missing or not properly configured. The key message is:

"No suitable driver found for jdbc:hive2://"

Possible Causes and Solutions:

1. Missing JDBC Driver:

   • Ensure the Hive JDBC driver (hive-jdbc-<version>.jar) is available in the classpath.
   • If using Spark with Livy, place the JAR in the Livy classpath.

2. Incorrect Driver Configuration:

   • Verify that the connection string is correctly formatted.
   • Ensure required dependencies (hadoop-common, hive-service, etc.) are present.

3. SSL TrustStore Issue:

   • The error references an SSL truststore (sslTrustStore=/opt/cloudera/security/jssecacerts).
   • Check if the truststore path is correct and contains the necessary certificates.

4. Principal Issue (Kerberos Authentication):

   • The connection uses a Kerberos principal 
   • Ensure Kerberos is correctly configured (kinit might be needed).
