Rename cannot overwrite non empty destination directory /yarn/nm/usercache/hdfs/filecache/812

Using CDH 5.4.7-1.cdh5.4.7.p0.3, when I run multiple mapreduce jobs one after another, eventually one of the jobs will fail with this stack trace:

The number in the path varies, but restarting the failed job does not get rid of the error.

 

I have tried to set set the yarn.nodemanager.localizer.cache.target-size-mb to 0, restarting YARN, and waiting until after the cleanup, but it doesn't help.

 

The file /yarn/nm/usercache/hdfs/filecache/812 does not seem to exist before/after running the job.

 

Has anybody experienced this, or have an explanation as to why it happens?

The error was initially encountered in an older version of CDH, and it disappeared when we also updated the client to the same version.
