Hbase Hortonworks NamespaceNotFoundException

如何解决Hbase Hortonworks NamespaceNotFoundException

我想使用 Hortonworks 库 (https://mvnrepository.com/artifact/com.hortonworks/shc/1.1.1-2.1-s_2.11) 从 Spark 连接到 HBase。 我将配置文件添加到 spark (hbase-site.xml) 中，该文件具有与我的 HBase 完全相同的属性。

这是完整的命令：

spark-shell --jars /home/me/Downloads/spark-hbase-connector_2.10-1.0.3.jar,/home/me/Downloads/hbase-spark-2.0.2.3.1.0.6-1.jar,/home/me/Downloads/spark-sql_2.12-2.4.7.jar,/home/me/Downloads/shc-core-1.1.1-2.1-s_2.11.jar,/home/me/Downloads/audience-annotations-0.13.0.jar --packages org.apache.hbase:hbase:2.4.1 --files /usr/local/spark/conf/hbase-site.xml

我尝试遵循 Hortonworks 插入方法的这个示例： https://github.com/sparkbyexamples/spark-hbase-hortonworks-examples/blob/master/src/main/scala/com/sparkbyexamples/spark/dataframe/hbase/hortonworks/HBaseSparkInsert.scala

我收到以下错误：

示例类中指定的命名空间是“default”。在我的 HBase 中，我也得到：

NAMESPACE                                                                                           
default                                                                                             
hbase      

如果错误是 NamespaceNotFoundException 但我有这个命名空间，可能是什么问题导致了错误？
