在DfsBroker上配置hypertable运行时出现hadoop无法启动错误

Question

我只是尝试在hadoop上安装hypertable，遵循官方文档，首先我在CentOS 6.5-32位节点上以说服-分发模式部署了cdh4

然后按照hypertable官方文档在hadoop上安装hypertable

当我跑的时候

cap start -f Capfile.cluster

get DfsBroker没有出现错误

我在/opt/hypertable/0.9.7.16中检查DfsBroker.hadoop.log，得到以下内容

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

但是我已经设置了JAVA_HOME，并且我测试java运行正常。

java --version  

我试着单独运行jrun，它没有提示exec: java : not found

我在google之后也看到过类似的问题

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

只需获取

Hypertable successfully configured for Hadoop cdh4

因此，如果有人能就这个问题给我一个提示，我将不胜感激

在启动集群之前，你必须运行：

cap fhsize -f Capfile.cluster

然后，您可以检查所有目录是否已正确设置：

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

而且java版本也应该可以工作。

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