我已经安装了Spark在Windows机器（独立），并试图使用Spark应用程序连接VM中可用的HDP 2.6配置单元Metastore。SparkSQL错误：org.apache.hadoop.hive.ql.metadata.HiveException：无法实例org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
我已经使用NAT作为网络适配器HDP 2.6 VM。 虽然我想蜂巢metastore（HDP 2.6 VM）从星火应用连接（Windows机器在本地模式），我收到以下错误消息。
17/08/12 17:00:16 INFO metastore: Waiting 1 seconds before next connection attempt.

hiveContext.sql("FROM default.sample_07 SELECT code, description, total_emp, salary").collect().foreach(println)
}
}
任何人都可以请帮我解决这个问题？
