Spark is a cluster computing platform that originated at the University of California, Berkeley Amplab. It is based on memory calculation, from many iterations of batch processing, eclectic data warehouse, flow processing and graph calculation and other computational paradigm, is a rare all-round player. Spark has formally applied to join the Apache incubator, from the "Spark" of the laboratory "" EDM into a large data technology platform for the emergence of the new sharp. This article mainly narrates the design thought of Spark. Spark, as its name shows, is an uncommon "flash" of large data. The specific characteristics are summarized as "light, fast ...

[YORK server channel May 20 news cloud computing and other application trends under the influence of data center construction is growing at an unprecedented speed. In a growing data center, energy consumption again becomes a key factor in data center costs, and as a result, low-power server products have drawn the attention of all parties. There are already Dell, HP and many other mainstream server vendors have introduced low-power server products. In the low-power server industry chain, chip market is undergoing new changes, the current low-power market, the main processor platforms include Intel and ARM. To these two manufacturers to ...

The most interesting place for Hadoop is the job scheduling of Hadoop, and it is necessary to have a thorough understanding of Hadoop's job scheduling before formally introducing how to build Hadoop. We may not be able to use Hadoop, but if the principle of the distributed scheduling is fluent Hadoop, you may not be able to write a mini hadoop~ when you need it: Start Map/reduce is a part for large-scale data processing ...

1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...
