They were quick enough to understand the real value possessed by Sparks such as Machine Learning and interactive querying. Industry leaders such as Amazon, Huawei, and IBM have already adopted Apache Spark. The firms that were initially based on Hadoop, such as Hortonworks, Cloudera, and MapR,...
Spark achieves fault tolerance using the DAG by using a technique called lineage, which is the record of the transformations that were used to create an RDD. When a partition of an RDD is lost due to a node failure, Spark can use the lineage to rebuild the lost partition....
