WebTachyon: 1. A hypothetical particle faster than light. 2. An up and coming superhero with superspeed. Though Johnathon Phillips would love to have a peaceful life after college, hostile governments, mad scientists, and supervillains have made it difficult. Perhaps life would be easier if we wasn't Tachyon, the fastest man in his hometown. WebAlluxio, formerly Tachyon, is a memory speed virtual distributed storage system and leverages memory for storing data and accelerating access to data in different storage systems. Many organizations and deployments use Alluxio with Apache Spark, and some of them scale out to over PB’s of data. Alluxio can enable Spark to be even more effective,...

During the past several years, Spark has significantly changed the landscape of big data computing. It improves performance of various applications dramatically. However, in certain Spark use cases, the bottleneck is in the I/O stack. In this talk, we will introduce Tachyon, a distributed memory-centric ...
WebSpark will run one task for each slice of the cluster. Typically you want 2-4 slices for each CPU in your cluster. Normally, Spark tries to set the number of slices automatically based on your cluster. However, you can also set it manually by passing it as a second parameter to parallelize (e.g. sc.parallelize (data, 10) ). External Datasets Scala WebA Spark application with dynamic allocation enabled requests additional executors when it has pending tasks waiting to be scheduled. This condition necessarily implies that the existing set of executors is insufficient to simultaneously saturate all tasks that have been submitted but not yet finished. Spark requests executors in rounds.
