I have a 5 Node MapR Cluster, and I am most of time submitting my spark application to yarn.
I see one of the Nodes is Inactive every now and then and Is marked as Unhealthy nodes with the following error
1/1 local-dirs are bad: /tmp/hadoop-mapr/nm-local-dir;
My question Is, why Is this folder frequently filling up, why is it used? and how can i change the folder to a disk with more space.
