I faced the same issue (Spark for Hive acid tables )and I can able to manage with JDBC call from Spark. Maybe I can use this JDBC call from spark until we get the native ACID support from Spark. Please refer the below link for code and steps to achieve the same. https://github.com/Gowthamsb12/Spark/blob/master/Spark_ACID Stackoverflow Answer - https://stackoverflow.com/questions/50254590/how-to-read-orc-transaction-hive-table-in-spark/56233158#56233158 Thanks Gowtham
