从mssql环境进入同样具有spark访问权限的配置单元环境。正试图用rstudio和r（有时python使用rpython）来代替我以前使用t-sql的一些东西，以及我以前从未做过的一大堆事情。
为了使这项工作，我将需要能够读和写回配置单元数据库。
我已经使用spark和r软件包SparkyR进行了连接，可以使用带有spark连接的r软件包dbi连接到我们的hive群集，并将数据拉入rDataframe：

sc <- spark_connect(master = "yarn-client", spark_home="/usr/hdp/current/spark-client", config = config)
result3 <- dbGetQuery(sc, "select * from sampledb.sampletable limit 100")

上面的代码每次都有效。我还可以使用dbgetquery在引用的sql语句的上下文中在db中创建表，这样就不会出现写权限问题。
但是，当我尝试将数据从r帧写回hive集群时，如下所示：

dbWriteTable(conn = sc, name = "sampledb.rsparktest3", value = result3)

它运行时没有错误，但表没有显示，我无法查询它。
如果我再次尝试写入表，会出现以下错误：

> dbWriteTable(conn = sc, name = "sampledb.rsparktest3", value = result3)
Error in .local(conn, name, value, ...) : 
Table sampledb.rsparktest3 already exists

知道会发生什么吗？除了dbi还有更好的方法吗？
提前感谢您的帮助！
下面是我运行这些语句时的整个rstudio控制台日志：

> result3 <- dbGetQuery(sc, "select * from sampledb.sampletable limit 100")
> dbWriteTable(conn = sc, name = "sampledb.rsparktest3", value = result3)
> result3y <- dbGetQuery(sc, "select * from sampledb.rsparktest3 limit 2")
