How to run Spark

Example 1: The famous WordCounter

spark-submit --class com.broodcamp.spark.WordCounter --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/input.txt

*Now let's try to run Spark by processing data from https://grouplens.org/datasets/movielens/100k/.

Example 2: Compute the average rating given by a user

UserId MovieId Rating TimeStamp

196 242 3 881250949

spark-submit --class com.broodcamp.spark.RatingsAverage --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u.data

Example 3: Old five-star movies

Example 4: Most rated one-star movies

spark-submit --class com.broodcamp.spark.WorstMovies --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u.data src/main/resources/u.item

spark-submit --class com.broodcamp.spark.WorstMoviesV2 --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u.data src/main/resources/u.item

Example 5: Get the square of each element in the set

spark-submit --class com.broodcamp.spark.NumberSquare --master local target/spark-job-0.0.1-SNAPSHOT.jar

Example 6. Movie recommendation

spark-submit --class com.broodcamp.spark.MovieRecommendationsALS --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u-ml.data src/main/resources/u.item

spark-submit --class com.broodcamp.spark.MovieRecommendationsALS2 --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/sample_movielens_ratings.txt src/main/resources/u.item

Example 6. Cassandra integration

spark-submit --class com.broodcamp.spark.CassandraIntegration --packages com.datastax.spark:spark-cassandra-connector_2.11:2.4.0 --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u.user

Example 7. MongoDB integration

spark-submit --class com.broodcamp.spark.MongoIntegration --packages org.mongodb.spark:mongo-spark-connector_2.11:2.4.0 --master local target/spark-job-0.0.1-SNAPSHOT.jar src/main/resources/u.user
