Hi I imported a table from mssql server with Sqoop 1.4.5 in parquet format.
But when I try to load it from Spark shell, it throws error like :
scala> val df1 = sqlContext.load("/home/bipin/Customer2")
scala.collection.parallel.CompositeThrowable: Multiple exceptions thrown
during a parallel computation: java.lang.NullPointerException

I looked at the sqoop parquet folder and it's structure is different than
the one that I created on Spark. How can I make the parquet file work ?
