1.Change 'text' args back to 'sequence'
2.use "SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'" to replace the former, which is constitutionally the same as former "DELEMITED FIELDS TERMINITED BY ','" to avoid the sql error in Spark 2.0(caused by PR apache/spark#13068)
3.Upgrade Hive version to 0.14 to gain OpenCSVSerde(Since Hive 0.14) support
