Today, we While Pig is very versatile and extensible, there are certain tasks that are better performed elsewhere (some of which are specific to the data processing platform, Hadoop). At the Strata event, we're featuring Cisco UCS servers and Cisco Nexus switches for Big Data as well as our Cisco TES support for Hadoop. Tim Jones, author of Pig in Action. Of reviews others have written for this and other books in this space, along with my personal experience with other Manning publications such as "Spring in Action", "Java Persistence with Hibernate", and "Hadoop in Action". Hadoop支持非java预言来编写程序，这就会用到Streaming的通用API。HadoopStreaming使用流与程序进行交互。从STDIN输入数据，输出到STDOUT。数据必须为文本，而且每一行被视为一条记录。 用Streaming处理键-.. Hive is built on Hadoop and uses Hadoop's storage and execution modules. To see Cisco TES and Hadoop in action, check out this online demo here. Even if you have never defined any counters in hadoop, you can see some of them each time you are running an hadoop job. In terms of storage Hive can use any file system supported by Hadoop, although HDFS is by far the most common. To do so before booting the cluster, add --bootstrap-action="s3://elasticmapreduce/bootstrap-actions/configure-hadoop" \ --args "-m,mapred.tasktracker.map.tasks.maximum=4,-m,mapred.tasktracker.reduce.tasks.maximum=2". HIGHLIGHT Hadoop in Action is an example-rich tutorial that shows developers how to implement data-intensive distributed computing using Hadoop and the Map- Reduce framework.
