Hadoop网站监控升级问题 [英] Hadoop upgrade issue with web monitoring

问题描述

我刚刚从0.19升级到0.20，一切似乎都正常，但网络监控工具无法正常工作：

给我一​​个 404 。

同样代表作业追踪工具

任何想法在哪里看？

解决方案

基本上从零开始重新安装Hadoop 0.20.2。
Nota：没有使用Nutch1.2构建来安装它，使其干净，可能是。

另外要注意的是：
+ startup集群的速度要慢得多，所以在dfs运行之前必须等待一段时间（例如1分钟），这样可能会导致它无法正常工作的印象
+ mapred启动的等待dfs运行并需要自己的时间。

最后一切都很顺利。

I just upgraded from 0.19 to 0.20 everything seems fine however the web monitoring tool doesn't work any more:

http://mydomain.com:50070/webapps/hdfs/dfshealth.jsp

Gives me a 404.

Same stands for the job tracking tool

Any idea where to look at ?

解决方案

Basically re-installed Hadoop 0.20.2 from scratch. Nota : did not use the Nutch1.2 build to install to have it clean and is probably.

Also to note : + startup of cluster is much slower, so one has to wait some time (eg 1 minute) before the dfs is running so it may give the impression it is not working + same stand for the start of mapred which does wait for the dfs to run and takes its own time.

Eventually everything went fine.
