>                 Key: SPARK-26712
>                 URL: https://issues.apache.org/jira/browse/SPARK-26712
>             Project: Spark
>          Issue Type: Improvement
>          Components: Shuffle
>    Affects Versions: 2.1.0, 2.4.0
>            Reporter: liupengcheng
>            Priority: Major
>
> Currently, `ExecutorShuffleInfo` can be recovered from file if NM recovery enabled, however, the recovery file is under a fixed directory, which may be unavailable if Disk broken. So if a NM restart happen(may be caused by kill or some reason), the `ExecutorShuffleInfo` will lost, and causes the shuffleservice unavailble even if there are executors on the node.
> This may finally cause job failures(if node or executors on it not blacklisted), or at least, it will cause resource waste.(shuffle from this node always failed.)
> For long running spark applications, this problem may be more serious.
> So I think we should support multi directories(multi disk) for this recovery. and change to good directory and when the disk of current directory is broken.
