windowns运行环境搭建: 第一步：安装Cygwin openssh - the Net category 组件 启动ssh 后启动ssh 启动Cygwin 运行 $ ssh-host-config -y 提示输入CYGWIN=ntsec tty 启动服务: $ cygrunsrv -S sshd 输入 hosts也需要注意配置上名称和ip，hadoop会使用机器名做启动 运行环境配置 hadoop 0.20.2 配置 hive 0.7.0 配置 环境变量 javax.jdo.option.ConnectionURL javax.jdo.option.ConnectionDriverName 文件夹设置 set tmp folder hive.exec.scratchdir eclipse debug 调试环境 a.jline windows问题 b.配置文件conf/ c.metastrore 问题 d.-Djava.io.tmpdir=/tmp 代码 NOTICE Apache Hive Copyright 2008-2011 The Apache Software Foundation This product includes software developed by The Apache Software Foundation (/). ant ivy thrift datanucleus This product includes software developed by The JDBM Project (/).
