【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> "大数据"是一个体量特别大，数据类别特别大的数据集，并且这样的数据集无法用传统数据库工具对其内容进行抓取、管理和处理。 "大数据"首先是指数据体量(volumes)大，指代大型数据集，一般在10TB规模左右，但在实际应用中，很多企业用户把多个数据集放在一起，已经形成了PB级的数据量；其次是指数据类别(variety)大，数据来自多种数据源，数据种类和格式日渐丰富，已冲破了以前所限定的结构化数据范畴，囊括了半结构化和非结构化数据。接着是数据处理速度（Velocity）快，在数据量非常庞大的情况下，也能够做到数据的实时处理。最后一个特点是指数据真实性（Veracity）高，随着社交数据、企业内容、交易与应用数据等新数据源的兴趣，传统数据源的局限被打破，企业愈发需要有效的信息之力以确保其真实性及安全性。  亚马逊网络服务（AWS）、大数据科学家JohnRauser提到一个简单的定义：大数据就是任何超过了一台计算机处理能力的庞大数据量。 研发小组对大数据的定义："大数据是最大的宣传技术、是最时髦的技术，当这种现象出现时，定义就变得很混乱。" Kelly说："大数据是可能不包含所有的信息，但我觉得大部分是正确的。对大数据的一部分认知在于，它是如此之大，分析它需要多个工作负载，这是AWS的定义。当你的技术达到极限时

Where should I put Velocity template files for a command line utility built with Maven?

由 爷，独闯天下 提交于 2019-12-14 02:34:06
问题 I have a small command line utility project that I'm using Maven to manage. The utility is a very simple app to populate a Velocity template and dump the results to a new file. My problem is where to put my Velocity templates. When I put them in src/test/resources/foo/bar/baz , mvn test fails because it can't find the referenced template, even though it is clearly there in target/classes/foo/bar/baz , which is where the .class file for the test and the class under test are located.
