我正在尝试通过Intelliji连接到Hive。我正在使用Scala 2.11.4版本，spark-core，spark-hive，spark-sql的版本是2.1.1。这是我用来从Windows M / C远程连接的代码片段。连接时出现以下错误，有人可以帮助我解决此问题吗？
注意:当我阅读一些线程时，他们提到了检查tmp的许可，在本例中为/ tmp / hive / warehouse。它对我用来连接的用户xyz具有适当的权限。使用此功能ID，我可以从一台unix服务器手动连接。我什至尝试使用spark.sql(“显示数据库”)，但这是相同的错误。

最佳答案
18/05/02 23:59:13 INFO SharedState: spark.sql.warehouse.dir is not set,
很明显，您的
spark.sql.warehouse.dir没有设置，请设置为消除上述问题val warehouseLocation = "file:${system:user.dir}/spark-warehouse"
val spark = SparkSession
.builder()
.appName("***")
.master("***")
.config("spark.sql.warehouse.dir", warehouseLocation)
.enableHiveSupport()
.getOrCreate()
希望这对您有帮助
