Spark Data Top Up

The Big data field of the 2014, Apache Spark (hereinafter referred to as Spark) is undoubtedly the most attention. Spark, from the hand of the family of Berkeley Amplab, at present by the commercial company Databricks escort. Spark has become one of ASF's most active projects since March 2014, and has received extensive support in the industry-the spark 1.2 release in December 2014 contains more than 1000 contributor contributions from 172-bit TLP ...

In the past few years, the use of Apache Spark has increased at an alarming rate, usually as a successor to the MapReduce, which can support thousands of-node-scale cluster deployments. In the memory data processing, the Apache spark is more efficient than the mapreduce has been widely recognized, but when the amount of data is far beyond memory capacity, we also hear some organizations in the spark use of trouble. Therefore, with the spark community, we put a lot of energy to do spark stability, scalability, performance, etc...

At the moment, http://www.aliyun.com/zixun/aggregation/13383.html ">spark has gained popularity, and a distributed computing approach based on map reduce makes spark similar to Hadoop, 　　It is more versatile than Hadoop, with more efficient iterations and more fault-tolerant capabilities, and future spark will be a very successful parallel computing framework. "Editor's note" author Mikio Braun is Berlin industrial big ...

3721.html ">2014 April 19" China Spark Technology Summit (Spark Summit Chinese 2014) will be held in Beijing, home and abroad Apache Spark community members and business users will be in Beijing for the first time. 　　 　　Spark contributors and front-line developers of Amplab, Databricks, Intel, Taobao, and NetEase will share their spark project experience and best practices in the production environment. Spark as a ...

As a common parallel processing framework, http://www.aliyun.com/zixun/aggregation/13383.html ">spark has some advantages like Hadoop, and Spark uses better memory management, In iterative computing has a higher efficiency than Hadoop, Spark also provides a wider range of data set operation types, greatly facilitate the development of users, checkpoint application so that spark has a strong fault tolerance, many ...

The authors observed that http://www.aliyun.com/zixun/aggregation/14417.html ">apache Spark recently issued some unusual events databricks will provide $ 　　14M USD supports Spark,cloudera decision to support Spark,spark is considered a big issue in the field of large data. The beautiful first impressions of the author think that they have been used with Scala's API (spark).

MapReduce provides powerful support for large data mining, but complex mining algorithms often require multiple mapreduce jobs to be completed, redundant disk read and write overhead and multiple resource request processes exist between multiple jobs, making the implementation of MapReduce based algorithms have serious performance problems. The Up-and-comer spark benefit from its advantages in iterative calculation and memory calculation, it can automatically dispatch complex computing tasks, avoid the intermediate result of disk read and write and resource request process, it is very suitable for data mining algorithm. Tencent TDW Spark Platform base ...

The authors observed that Apache Spark recently sent some unusual events, Databricks will provide $14m USD support Spark,cloudera decided to support Spark,spark is considered a big issue in the field of large data. A good first impression the author believes that he has been dealing with Scala's API (spark using Scala) for some time, and, to tell you the truth, was very impressive at first because spark was so small and good. The basic abstraction is the projectile ...

Http://www.aliyun.com/zixun/aggregation/13383.html ">spark is a cluster computing platform originating from the Amplab of the University of California, Berkeley, which is based on memory computing and has more performance than Hadoop , even with disk, the calculation of the iteration type will increase by 10 times times. Spark is a rare all-round player, starting from multiple iterations, eclectic data Warehouse, stream processing and graph calculation. Spar ...
