使用凤凰连接器将Spark数据帧写入Hbase

Question

我有一个Hive表，它指向Hbase表。我有一个火花作业，它创建具有等于hbase表的架构的数据集。我使用以下命令将此数据帧保存到hbase表。

sql.write().format("org.apache.phoenix.spark")
    .mode(SaveMode.Overwrite).option("table", targetTable)
    .option("zkUrl", "localhost:2181:/hbase-unsecure)
    .insertInto(targetTable);

执行时，我得到下面的错误。

java.lang.NullPointerException

非常感谢您的帮助。

我正在使用spark2和HDP群集。
