Because I really get bored of getting kind of exception "Last packet sent to the server was .. ago" Any help would be appreciated. 回答1: You can keep the connection alive by doing the following: On Aliases->Modify the Selected Alias (pencil icon)-> Properties-> Connection (tab) Check Enable Keep-Alive and enter a simple query, in PostgreSQL I use SELECT 1; , in Oracle should be something like

The installer is created successfully but I don't know how ho handle Squirrel's events inside my app, as stated in the docs I've added this to the entry point of my app: var handleStartupEvent = function () { if ( process . platform !== 'win32' ) { return false ; } var squirrelCommand = process . argv [ 1 ]; switch ( squirrelCommand ) { case '--squirrel-install' : case '

环境: 1台NameNode服务器,2台DataNode服务器 安装步骤 ①:配置/etc/hosts文件:实现集群内部的DNS解析,无需查询DNS服务器,当访问远程主机时首先查询hosts文件是否有配置,如果配置则直接按照指定的IP直接访问远程主机(实际规模较大的hadoop集群一般会配置DNS服务器进行统一管理) 修改linux主机的主机名:/etc/sysconfig/network文件的HOSTNAME字段的值即可(注意重启才可永久生效) hostname newName:重启之后就会失效 hosts文件:注意每个节点最好共享同1份hosts文件 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.174.142 NameNode 192.168.174.143 DataNode_01 192.168.174.145 DataNode_02 测试hosts文件: [squirrel@DataNode_02 ~]\$ ping DataNode_01 PING DataNode_01 (192.168.174.143)

文章说明:因Linux平台再GUI页面通过IDE进行Hadoop开发,会导致Linux在GUI上极度消耗资源,对于一些配置不是很高的PC,可能会出现卡顿的情况,非常影响程序编写,本文就详细介绍如何在windows平台进行hadoop开发,希望对各位学习Hadoop的同学优异 工具: hadoop eclipse插件:hadoop-eclipse-plugin-2.7.3.jar hadoop windows平台支持组件:winutils.exe hadoop 底层依赖库:hadoop.dll 上述工具下载地址: 下载地址 Hadoop版本 : hadoop-2.7.3 配置步骤: 启动hadoop : start-yarn.sh、start-dfs.sh windows本地配置Linux的主机IP映射:(不配置直接使用IP也行) 将hadoop-eclipse-plugin-2.7.3.jar放进eclipse的plugins目录,启动eclipse eclipse配置Hadoop 切换MapReduce视图可以看到HDFS文件系统的信息 运行MapReduce程序 配置HADOOP环境变量:主要将bin、sbin放入PATH路径 将winutils.exe放在bin目录,hadoop.dll放在windows System32目录 测试代码 import java.io
