apache spark rdd internals



:: DeveloperApi :: An RDD that provides core functionality for reading data stored in Hadoop (e.g., files in HDFS, sources in HBase, or S3), using the older MapReduce API (org.apache.hadoop.mapred).param: sc The SparkContext to associate the RDD with. It is an Immutable, Fault Tolerant collection of objects partitioned across several nodes. Sometimes we want to repartition an RDD, for example because it comes from a file that wasn't created by us, and the number of partitions defined from the creator is not the one we want. ifPartitionNotExists flag Demystifying inner-workings of Apache Spark. To address this, the Spark 0.7 release introduced a Java API that hides these Scala <-> Java interoperability concerns. Browse other questions tagged apache-spark pyspark apache-spark-sql or ask your own question. Resilient Distributed Datasets (RDD) is a fundamental data structure of Spark. All of the scheduling and execution in Spark is done based on these methods, allowing each RDD to implement its own way of computing itself. We learned about the Apache Spark ecosystem in the earlier section. These difficulties made for an unpleasant user experience. Apache Spark - RDD.

It is an immutable distributed collection of objects. Indeed, users can implement custom RDDs (e.g. The project contains the sources of The Internals Of Apache Spark online book. Many of Spark's methods accept or return Scala collection types; this is inconvenient and often results in users manually converting to and from Java types.
