作者简介
Lars George,HBase项目组成员,他是cloudera的解决方案架构师,提供了关于Hadoop和HBase的技术支持、咨询服务和培训工作。他曾经在多个不同的Hadoop用户组会议发言,并且在如布鲁塞尔的自由及开源软件开发者欧洲会议(FOSDEM)这样的大型会议中发言。
AI导读
核心看点
  • 本书深入解析HBase底层架构,涵盖存储格式、预写日志机制及后台进程原理,帮助读者理解数据在分布式集群中的持久化与一致性保障机制,为系统稳定性提供理论支撑。
  • 提供从环境部署到高级调优的全流程指导,包括集群配置、节点管理、批量数据导入及表拷贝等运维操作,同时详解如何利用MapReduce框架与HBase进行集成开发。
  • 强调行键设计与数据模型的最佳实践,指导开发者如何避免热点数据问题,提升查询性能,并介绍Coprocessor等高级特性,助力构建高效、可扩展的大数据存储解决方案。
读者共识
  • 尽管版本陈旧且翻译存在瑕疵,但本书在HBase架构原理、存储机制及底层实现方面的讲解依然具有极高的参考价值,是深入理解该技术不可替代的经典之作。
  • 读者普遍认为书中关于行键设计、数据模型优化及集群调优的经验总结极具实战意义,能有效帮助开发者避开常见陷阱,提升系统性能与稳定性。
  • 多数反馈指出书中部分代码示例已过时,且缺乏最新特性的介绍,建议读者将其作为原理学习的辅助材料,具体开发操作务必以官方最新文档为准。
精彩摘录
  • "You should think about rows and columns not being arranged like the classic spreadsheet model, but rather use a tag metaphor, that is, information is available under a specific tag."
  • "Every column value, or cell, either is timestamped implicitly by the system or can be set explicitly by the user. This can be used, for example, to save multiple versions of a value as it changes over time. Different versions of a cell are stored in decreasing time-stamp order, allowing you to read "
  • "There is also the option to run client-supplied code in the address space of the server.The server-side framework to support this is called coprocessors."
  • "The data is stored in store files, called HFiles, which are persistent and ordered immut-able maps from keys to values. Internally, the files are sequences of blocks with a block index stored at the end."
  • "There are three major components to HBase: the client library, one master server, and many region servers."
  • "A more critical feature is the so-called delayed allocation, and it is recommended that you turn it off for Hadoop and HBase use. Delayed allocation keeps the data in memory and reserves the required number of blocks until the data is finally flushed to disk."
  • "HBase implicitly assumes that data is stored in a reliable manner by the filesystem. It has no added means to replicate data or even maintain copies of its own storage files. This functionality must be provided by the lower-level system."
  • "You could implement most of the filter functionality in your client code as well, but you would have to transfer much more data—something you need to avoid at scale."

hbase必看,仅有的几本书,不过覆盖还是挺全,但不深,有些地方还要看源码确认,翻译的有些地方前后不通,不知讲啥,需要查看原版,版本有点旧了,希望出新版了
一方面继承了XXX Definitive Guide冗长没人味的传统,另一方面继承了汉译技术书语死早的传统
读了核心的几章,写的还可以,就是老外写的书太冗长了。另外,译者都不会说中国话么?看一句话想半天才知道啥意思。
了解HBase设计和原理
走马观花过了一遍,了解了大概脉络,留待以后有需要时细翻。
比较坑的点 1.源码默认是第二版的,第一版需要到这里下载https://github.com/larsgeorge/hbase- book/releases/tag/rev1 2.用的https://archive.apache.org/dist/hbase/hbase-0.90.6/ ,没有 找到0.91的 3.运行第七章的时候,要安装与HBase 0.90.6兼容的Hadoop 0.20.205.0 -下载hadoop https://archive.apache.org/dist/hadoop/common/hadoop-0.20.205.0/, -按照下面的文档安装:https://github-wiki-see.page/m/bertram-zbc/Hadoop-Class/wik
版本比较老了,挑着看些原理性的东西
书挺好,太旧了,还是直接看文档吧
目前需要精读1,8,9章
匆匆翻了一遍,讲了很多,又好像什么都没讲_(:з」∠)_
