DataNode启动失败的解决办法

作者阿里云代理 文章分类 分类:linux图文教程 阅读次数 已被围观 2287

start all没有报错,可是发现这NameNode的webUI上面DataNode没有挂上。

进入DataNode查看日志发现下面问题。


datanode 进程没有起来

NodeManager启动过一段时间退出了。

过错 java.io.IOException: No services to connect, missing NameNode address.

这个过错前面还有一个正告日志:

NodeManager 过了一会也挂了

可能是DataNode忘掉装备装备常规文件了。

core-site.xml - 导致DataNode进程衔接不到master 9000端口

yarn-site.xml - 导致NodeManager屡次重试衔接本机8031端口(yarn resourcetracker),没有装备的默认值。


这属于两个分开的问题,最终在进行了如下改动。

core-site.xml 设置fs.defaultFS指定为集群namenode url。

yarn-site.xml 设置yarn.resourcemanager.hostname指定值为resourcemanager的主机,当然也可以直接修正yarn.resourcemanager.resource-tracker.address为RM主机:端口号。


重跑一下NodeManager进程(不建议跑stop-all和start-all.sh,会把整个集群重启)。

查看NameNode WebUI

没启动的DataNode重新衔接集群了。
