我正在尝试使用以下命令在运行Ubuntu的本地计算机上挂载hdfs：—
sudo mount -t nfs -o vers=3,proto=tcp,nolock 192.168.170.52:/ /mnt/hdfs_mount/ 但我得到这个错误：
mount.nfs: mount system call failed
输出为
rpcinfo -p 192.168.170.52
是
program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 48435 status 100024 1 tcp 54261 status 100005 1 udp 4242 mountd 100005 2 udp 4242 mountd 100005 3 udp 4242 mountd 100005 1 tcp 4242 mountd 100005 2 tcp 4242 mountd 100005 3 tcp 4242 mountd 100003 3 tcp 2049 nfs
输出为
showmount -e 192.168.170.52
是
Export list for 192.168.170.52: / *
我也尝试join
<property> <name>hadoop.proxyuser.root.groups</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.root.hosts</name> <value>*</value> </property>
在位于/etc/hadoop/conf.pseudo的core-site.xml文件中。 但它没有工作。
输出： –
sudo mount -v -t nfs -o vers=3,proto=tcp,nolock 192.168.170.52:/ /mnt/hdfs_mount/
是：—
mount.nfs: timeout set for Thu Jun 29 09:46:30 2017 mount.nfs: trying text-based options 'vers=3,proto=tcp,nolock,addr=192.168.170.52' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.170.52 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=6 mount.nfs: trying 192.168.170.52 prog 100005 vers 3 prot TCP port 4242 mount.nfs: mount(2): Input/output error mount.nfs: mount system call failed
请帮我解决一下这个。
