Hi All,
I am using Saprk version 1.2 running locally. When I try to read a paquet
file I get below exception, what might be the issue?
Any help will be appreciated. This is the simplest operation/action on a
parquet file.
//code snippet//
val sparkConf = new SparkConf().setAppName("
Testing").setMaster("local[10]")
val sc = new SparkContext(sparkConf)
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
sqlContext.setConf("spark.sql.parquet.binaryAsString","true")
import sqlContext._
val temp = "local path to file"
val temp2 = sqlContext.parquetFile(temp)
temp2.printSchema
//end code snippet
//Exception trace
Exception in thread "main" java.lang.NullPointerException
