无法在Postgres中实例化外部Hive Metastore /在类路径中找不到驱动程序

Question

我正在将Cloudera CDH 6.3与Spark 2.4.4结合使用。 SparkConf（）具有连接到外部Hive Postgres Metastore的配置。在下面的Scala代码下运行

sqlc.sql("show databases")

...我遇到错误：

unable to instantiate hive metastore
org.datanucleus.exceptions.NucleusException of datastore driver ("org.postgresql.Driver") not found in the CLASSPATH. 
Check CLASSPATH specification and the name of the driver.

错误日志中提到了详细的日志。我尝试使用pyspark Spark SQL的以下代码中所示的相同Spark配置设置，并成功连接到外部Hive Metastore。最后包含build.sbt文件。非常赞赏如何使此Scala代码段连接到外部Hive Metastore的任何线索。

我尝试过的事情：

将hive-site.cml移动到spark / conf文件夹
将/ tmp / hive位置的权限更改为hdfs中的777
将postgresql-jdbc驱动程序从HIVE_HOME移至SPARK_HOME
Spark-env.sh已将SPARK_CLASSPATH导出到postgresql-jdbc驱动程序位置
尝试使用hiveContext.sql代替注释者提到的SQLContext.sql。仍然没有运气。

Scala代码段

val sparkConf = new SparkConf().
 setAppName("MQJMSReceiver").
 set("spark.debug.maxToStringFields", "10000").
 set("spark.hadoop.hive.exec.dynamic.partition.mode", "non-strict").
 set("spark.hadoop.hive.exec.dynamic.partition", "true").
 set("spark.sql.warehouse.dir","hdfs://xxx/user/hive/warehouse").
 set("hive.metastore.warehouse.dir", "hdfs://xxx/user/hive/warehouse").
 set("spark.sql.catalogImplementation", "hive").
 set("spark.sql.hive.metastore.sharedPrefixes","org.postgresql").
set("spark.hadoop.javax.jdo.option.ConnectionURL","jdbc:postgresql://xxx/hive").
 set("spark.hadoop.javax.jdo.option.ConnectionDriverName","org.postgresql.Driver").
 set("spark.hadoop.javax.jdo.option.ConnectionUserName","xxx").
 set("spark.hadoop.javax.jdo.option.ConnectionPassword","xxx").
 setMaster("local[*]").
 set("spark.streaming.stopGracefullyOnShutdown", "true")

val sc = new SparkContext(sparkConf)

val ssc = new StreamingContext(sc, Seconds(10))

val sqlc = new SQLContext(sc)
import sqlc.implicits._

sqlc.sql("show databases").show()
