hadoop - 在 hadoop 上配置超表运行时，DfsBroker 无法启动错误

Question

我只是尝试按照官方文档在hadoop上安装hypertable
首先我在 CentOS 6.5-32bit 节点上以 persudo-distribute 模式部署 cdh4

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

当我运行时

cap start -f Capfile.cluster

获取 DfsBroker 没有出现错误

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

但我 JAVA_HOME 已设置，我测试 java 运行正常

java --version  

我尝试单独运行 jrun ，它没有提示 exec: java : not found

我在谷歌之后看到了类似的问题

但我已经使用了所有我能找到的解决方案

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

刚刚明白

Hypertable successfully configured for Hadoop cdh4

所以如果有人能给我关于这个问题的提示，我将不胜感激

在启动集群之前，您必须运行:

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

并且java版本也应该可以工作

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