Don't fail when write to scratch dir results in error.

    Details

      Description

      Currently, a query fails when it tries to spill data to a disk and that write results in an error. This can happen for multiple reasons: a) no write permission, b) bad disk.

      The fix should do two things:

      • Check for write permissions on startup
      • Don't fail queries that hit an error at runtime (e.g. disk full) if there is another functional scratch disk that can be used instead.
