上面有两处有价值的错误信息：

EACCESsupervisor: child process was not spawned
这一处错误太过广泛，意思是不能生成子进程，但是不能生成子进程的原因太多了


org.apache.avro.AvroRemoteException: java.net.ConnectException: Connection refused (Connection refused)

这一处的错误是链接错误。也就是说上面错误的原因是因为这里被链接拒绝造成的，也就是说这里成为了关键。但是这个链接拒绝又有很多原因。比如端口被暂用，防火墙未关闭，ntp未同步时间等等，各种原因都可能造成。所以楼主还需要更详细的信息

需要找到error
可以通过下面命令过滤日志中的错误。
[mw_shl_code=bash,true]cat 日志|grep ERROR[/mw_shl_code]

这个问题上周搞定了，同事卸载重装的、然后chmod 777 -R /opt 这一类问题就没有了。
重装卸载一定要卸干净。

楼主说的对。
对于cloudera的安装，只要一步步按照步骤，一般不会出问题的。
如果是安装中出现异常，其实还是比较难搞的。
最好最粗暴的办法就是卸载干净重新安装。
如果想详细知道错误等，那就是十分耗时间了，而且可能还解决不掉。
