Greenplum-Spark-Connector java.util.NoSuchElementException: None.get - apache-spark

Question

My work Envorinments like bellow:
. Hadoop 2.7.2
. Spark 2.3.0
. Greenplum 6.8.1 <- I knew this version is latest.
and I have to create dataframe(RDD) from GPDB table. so, I have knew a "Greenplum-spark-connector". An architecture sounds good. but It does not work.
I tried like this:
spark/bin$spark-shell
--master spark://10.40.203.99:7077
--jars /data2/install_files/greenplum-spark_2.11-1.6.2.jar,/data2/install_files/postgresql-42.2.5.jar,/data2/install_files/jetty-io-9.2.26.v20180806.jar,/data2/install_files/jetty-server-9.2.26.v20180806.jar,/data2/install_files/jetty-util-9.2.26.v20180806.jar
--driver-class-path /data2/install_files/postgresql-42.2.5.jar
spark-shell
scala> scala> :paste
// Entering paste mode (ctrl-D to finish)
val ddf = spark.read.format("greenplum")
.option("url", "jdbc:postgresql://{GPDB_MASTER_IP}/{DATABASE_NAME}")
.option("server.port","12900")
.option("dbtable", "airports")
.option("dbschema","test")
.option("user", "user")
.option("password", "passw0rd!")
.option("partitionColumn","airportid")
.option("partitions",1)
.load()
// Exiting paste mode, now interpreting.

*It occurs "No Such element Exception". So, I try to check .jar-dependency. but I can get any Build-information via pom.xml.
How can I start to check this code...

Answer 1

The Greenplum Spark Connector version 1.6.2 is incompatible with Greenplum versions 6.7.1+. Currently we don't offer a connector for those versions of Greenplum. We'll be releasing a new Greenplum Spark Connector that supports all versions of Greenplum in the near future.
