> Gracefully handle loss of DiskStore files
> -----------------------------------------
>
> Key: SPARK-15736
> URL: https://issues.apache.org/jira/browse/SPARK-15736
> Project: Spark
> Issue Type: Bug
> Components: Block Manager
> Affects Versions: 1.6.0
> Reporter: Josh Rosen
> Assignee: Josh Rosen
>
> If an RDD partition is cached on disk and the DiskStore file is lost, then
> reads of that cached partition will fail and the missing partition is
> supposed to be recomputed by a new task attempt. In the current BlockManager
> implementation, however, the missing file does not trigger any metadata
> updates / does not invalidate the cache, so subsequent task attempts will be
> scheduled on the same executor and the doomed read will be repeatedly
> retried, leading to repeated task failures and eventually a total job failure.
> In order to fix this problem, the executor with the missing file needs to
> properly mark the corresponding block as missing so that it stops advertising
> itself as a cache location for that block.
