---------------------------------

Hi [~hex108], thanks for reporting this issue, What version is your code? YARN-3491 fixed
a race condition when a local disk turns from bad to good.

> A local disk turns from bad to good without NM initializes it(create /path-to-local-dir/usercache
and /path-to-local-dir/filecache). When localizing a container, container-executor will try
to create directories under /path-to-local-dir/usercache, and it will fail. Then container's
localization will fail.
