我正在尝试将 Spark DataFrame
这里的 df 是一个 Spark DataFrame。
我有没有漏掉什么?或者有没有更好的方法将它转换为
org.apache.spark.sql.DataFrame
转换为 sparklyr 表格 tbl_spark
。我试着使用 sdf_register
,但是遇到了以下错误。这里的 df 是一个 Spark DataFrame。
sdf_register(df, name = "my_tbl")
错误是指,
Error: org.apache.spark.sql.AnalysisException: Table not found: my_tbl; line 2 pos 17

我有没有漏掉什么?或者有没有更好的方法将它转换为
tbl_spark
?谢谢!
