Question

我只是尝试在hadoop上安装超级按照官方文档首先，我在CentOS 6.5-32bit节点上以persudo-distribute模式部署cdh4

然后按照超强的官方文档在hadoop上安装超文本

当我跑

时

cap start -f Capfile.cluster

得到DfsBroker没出现错误

我检查/opt/hypertable/0.9.7.16中的DfsBroker.hadoop.log 得到这个

/opt/hypertable/current/bin/jrun: line 113: exec: java: not found

但是我已经设置了JAVA_HOME并且我使用

测试java正常运行

java --version

我尝试单独运行jrun，它没有提示exec：java：not found

我在谷歌看到类似的问题

但我已经使用了我能找到的所有解决方案

/opt/hypertable/current/bin/set-hadoop-distro.sh cdh4

得到

Hypertable successfully configured for Hadoop cdh4

所以如果有人能给我一个关于这个问题的提示，我将不胜感激

在开始群集之前，您必须运行：

cap fhsize -f Capfile.cluster

然后您可以检查是否已正确设置所有目录：

ls -laF /opt/hypertable/current/lib/java/*.jar

并且java版本也应该起作用

/opt/hypertable/current/bin/jrun -version

当在hadoop上配置高效运行时，DfsBroker无法启动错误
