Description

When we run HoS job and if it fails for some errors, we are printing the exception message rather than exception toString(), for some exceptions, e.g., this java.lang.NoClassDefFoundError, we are missing the exception type information.

Failed to execute Spark task Stage-1, with exception 'org.apache.hadoop.hive.ql.metadata.HiveException(Failed to create Spark client for Spark session cf054497-b073-4327-a315-68c867ce3434: org/apache/spark/SparkConf)'

If we use exception's toString(), it will be as follows and make more sense.
