spark-csv를 사용하여 데이터를 DataFrame에로드합니다. 간단한 쿼리를 수행하고 내용을 표시하고 싶습니다.
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()
열이 잘린 것 같습니다.
scala> results.show();

열의 전체 내용을 표시하려면 어떻게합니까?
