I work a lot with avro files and everytime I start the spark shell I have to do these 5 imports
import org.apache.avro.generic.GenericRecord
import org.apache.avro.mapred.AvroKey
import org.apache.avro.mapreduce.AvroKeyInputFormat
import org.apache.hadoop.io.NullWritable
import org.apache.spark.SparkContext
is it possible that these are automatically imported into the spark shell everytime I start the spark-shell?
