您好，我正在尝试在 HADOOP(hadoop-2.7.0) 上设置 HBASE(hbase-0.98.12-hadoop2)
Hadoop 在 localhost:560070 上运行，运行良好。
我的 hbase-site.xml 如下所示
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>localhost</value>
</property>
<!-- <property>
<name>dfs.replication</name>
<value>1</value>
</property>-->
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
当我启动 ./start-hbase.sh 时，我在日志文件中收到此错误。

java.net.ConnectException: Call From bredgelinux-desktop/127.0.1.1 to localhost:54310 failed on connection exception: java.net.ConnectException: Connection refused
如果您有环回 IP 地址，则会发生此错误。请按照以下步骤纠正此错误:
第 1 步:从/etc/hosts 中删除带有 127.0.1.1 的行。
第 2 步:重新启动您的 hadoop 和 hbase 进程。
关于hadoop - hadoop 上的 Hbase 未在分布式模式下连接，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30374659/
我有一个模型:classItem项目有一个属性“商店”基于存储的值，我希望Item对象对特定方法具有不同的行为。Rails中是否有针对此的通用设计模式？如果方法中没有大的if-else语句，这是如何干净利落地完成的？ 最佳答案 通常通过Single-TableInheritance. 关于ruby-on-rails-Rails-子类化模型的设计模式是什么？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.co
我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i

我正在使用Sequel构建一个愿望list系统。我有一个wishlists和itemstable和一个items_wishlists连接表(该名称是续集选择的名称)。items_wishlists表还有一个用于facebookid的额外列(因此我可以存储opengraph操作)，这是一个NOTNULL列。我还有Wishlist和Item具有续集many_to_many关联的模型已建立。Wishlist类也有:selectmany_to_many关联的选项设置为select:[:items.*,:items_wishlists__facebook_action_id].有没有一种方法可以
我在Rails工作并有以下类(class):classPlayer当我运行时bundleexecrailsconsole然后尝试:a=Player.new("me",5.0,"UCLA")我回来了:=>#我不知道为什么Player对象不会在这里初始化。关于可能导致此问题的操作/解释的任何建议？谢谢，马里奥格 最佳答案 havenoideawhythePlayerobjectwouldn'tbeinitializedhere它没有初始化很简单，因为你还没有初始化它!您已经覆盖了ActiveRecord::Base初始化方法，但您没有调
我想设置一个默认日期，例如实际日期，我该如何设置？还有如何在组合框中设置默认值顺便问一下，date_field_tag和date_field之间有什么区别？ 最佳答案 试试这个:将默认日期作为第二个参数传递。youcorrectlysetthedefaultvalueofcomboboxasshowninyourquestion. 关于ruby-on-rails-date_field_tag，如何设置默认日期？[rails上的ruby]，我们在StackOverflow上找到一个类似的问
我将我的Rails应用程序部署到OpenShift，它运行良好，但我无法在生产服务器上运行“Rails控制台”。它给了我这个错误。我该如何解决这个问题？我尝试更新rubygems，但它也给出了权限被拒绝的错误，我也无法做到。railsc错误:Warning:You'reusingRubygems1.8.24withSpring.UpgradetoatleastRubygems2.1.0andrun`gempristine--all`forbetterstartupperformance./opt/rh/ruby193/root/usr/share/rubygems/rubygems
我使用的是Firefox版本36.0.1和Selenium-Webdrivergem版本2.45.0。我能够创建Firefox实例，但无法使用脚本继续进行进一步的操作无法在60秒内获得稳定的Firefox连接(127.0.0.1:7055)错误。有人能帮帮我吗？ 最佳答案 我遇到了同样的问题。降级到firefoxv33后一切正常。您可以找到旧版本here 关于ruby-无法在60秒内获得稳定的Firefox连接(127.0.0.1:7055)，我们在StackOverflow上找到一个类
我正在尝试从Postgresql表(table1)中获取数据，该表由另一个相关表(property)的字段(table2)过滤。在纯SQL中，我会这样编写查询:SELECT*FROMtable1JOINtable2USING(table2_id)WHEREtable2.propertyLIKE'query%'这工作正常:scope:my_scope,->(query){includes(:table2).where("table2.property":query)}但我真正需要的是使用LIKE运算符进行过滤，而不是严格相等。然而，这是行不通的:scope:my_scope,->(que
给定一个复杂的对象层次结构，幸运的是它不包含循环引用，我如何实现支持各种格式的序列化？我不是来讨论实际实现的。相反，我正在寻找可能会派上用场的设计模式提示。更准确地说:我正在使用Ruby，我想解析XML和JSON数据以构建复杂的对象层次结构。此外，应该可以将该层次结构序列化为JSON、XML和可能的HTML。我可以为此使用Builder模式吗？在任何提到的情况下，我都有某种结构化数据-无论是在内存中还是文本中-我想用它来构建其他东西。我认为将序列化逻辑与实际业务逻辑分开会很好，这样我以后就可以轻松支持多种XML格式。 最佳答案 我最
