Hadoop in LXC container error : YARN : 1/1 local-dirs are bad
问题 I have two hadoop instances running inside two lxc containers on the same host, a hadoop-master and a hadoop-slave1. While starting YARN & DFS on master I get this UNHEALTHY state for hadoop-slave1. For what I've found on the web it must be one of these two possibilities: Not enough disk space. Permission issue a. df -h says otherwise : Filesystem Size Used Avail Use% Mounted on /dev/sda5 91G 68G 19G 79% / none 4,0K 0 4,0K 0% /sys/fs/cgroup udev 3,8G 4,0K 3,8G 1% /dev tmpfs 769M 1,3M 768M 1%
