Hi Guys, I have struggled for a while on this seeming simple thing:
I have a sequence of timestamps and want to create a dataframe with 1 column. Seq[java.sql.Timestamp] //import collection.breakOut var seqTimestamp = scala.collection.Seq(listTs:_*) seqTimestamp: Seq[java.sql.Timestamp] = List(2015-07-22 16:52:00.0, 2015-07-22 16:53:00.0, ....., ) I tried a lot of ways to create a dataframe and below is another failed way: import sqlContext.implicits._ var rddTs = sc.parallelize(seqTimestamp) rddTs.toDF("minInterval") <console>:108: error: value toDF is not a member of org.apache.spark.rdd.RDD[java.sql.Timestamp] rddTs.toDF("minInterval") So, any guru could please tell me how to do this???? I am not familiar with Scala or Spark. I wonder if learning Scala will help this at all? It just sounds a lot of time of trial/error and googling. docs like https://spark.apache.org/docs/1.3.0/api/java/org/apache/spark/sql/DataFrame.html https://spark.apache.org/docs/1.3.0/api/java/org/apache/spark/sql/SQLContext.html#createDataFrame(scala.collection.Seq, scala.reflect.api.TypeTags.TypeTag) does not help. Btw, I am using Spark 1.4.
