我的工作环境如下：。hadoop 2.7.2版。spark 2.3.0版。greenplum6.8.1<-我知道这个版本是最新的。
我必须从gpdb表中创建dataframe（rdd）。所以，我知道一个“青梅Spark连接器”。建筑听起来不错。但它不起作用。
我试着这样：

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.

  • 出现“无此元素异常”。所以，我试着检查.jar依赖关系。但是我可以通过pom.xml获得任何构建信息。如何开始检查此代码。。。

greenplumSpark连接器版本1.6.2与greenplum版本6.7.1+不兼容。目前，我们不提供这些版本的greenplum连接器。我们将发布一个新的greenplumSpark连接器，支持所有版本的greenplum在不久的将来。
