我使用spark-csv加载数据到一个DataFrame。我想做一个简单的查询并显示内容:
val df = sqlContext.read.format("com.databricks.spark.csv").option("header", "true").load("my.csv")
df.registerTempTable("tasks")
results = sqlContext.sql("select col from tasks");
results.show()
山坳似乎被截断了:
scala> results.show();
+--------------------+
| col|
+--------------------+
