Manually creating the directory worked. This behavior was common to at least several nodes in the cluster.
The situation was resolved by removing and recreating all /disk?/yarn/local/filecache directories on all nodes.
It is unclear whether Yarn struggled with the number of files or if there were corrupt files in the caches. The situation was triggered by a node dying.
