问题描述
在文档，但尝试启动启动hadoop portmap服务的NFS服务时遇到错误:
Attempting to use / startup HDFS NFS following the docs, but running into error when trying to set up the NFS service starting the hadoop portmap service:
[root@HW02 hdfs]# service rpcbind stop
Redirecting to /bin/systemctl stop rpcbind.service
Warning: Stopping rpcbind.service, but it can still be activated by:

推荐答案
在调试另一个NFS网关问题时找到了答案，请参见 https://stackoverflow.com/a/57228283/8236733
Found answer while debugging another NFS gateway problem, see https://stackoverflow.com/a/57228283/8236733
TLDR :nfs网关服务已经在运行(默认情况下，显然是默认情况)，我认为阻止hadoop nfs3服务(jsvc.exec)启动的服务是(我假设)该服务的一部分已经在运行.如果您已经通过ambari管理集群，则为HDP3.1设置用于HDFS的NFS网关的文档不一定是最好的方法.
TLDR: nfs gateway service was already running (by default, apparently) and the service that I thought was blocking the hadoop nfs3 service (jsvc.exec) from starting was (I'm assuming) part of that service already running. The docs for setting up NFS Gateway for HDFS for HDP3.1 are not necessarily the best way to do it if you are already managing your cluster via ambari.
这篇关于HDFS NFS启动错误:"ERRORportmap.Portmap:无法启动服务器... ChannelException:无法绑定".的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
