That solved the issue! After restarting yarn, the node is shown as healthy now.
I’m installing HDP2.0 on Ubuntu 12.04 as a single node test setup. I got to the point where I’ve got HDFS and YARN installed and running. However the single datanode I’ve got shown as unhealthy in the YARN webapp. The message is
1/1 local-dirs turned bad: /grid/hadoop/hdfs/yarn/local;
I noticed that I didn’t create the directory. So I created it and updated ownership and access rights. Even after reboots and restarts of the different daemons, the node is still shown as unhealthy.
What additional things do I need to do to recover the datanode and get it ‘healthy’ again?
