Github user sarutak commented on the pull request: https://github.com/apache/spark/pull/1383#issuecomment-49255082 My PR handles IOException as fatal but I think it's not good because IOException is not always fatal. The problem I want to solve is IOException thrown when writing to and reading from local directory managed by DiskBlockManager are failed. In such case, I think it's almost caused by disk fault. So, is it better to exit when reading from or writing to local directory are failed?
