> Need a tool that will run read pipeline on a file downloaded from the cluster
> (that causes some exception), for local debugging. Needs to reproduce
> whatever environment necessary (in IO pipeline itself) from the cluster (e.g.
> allocation sizes in allocator, etc.). Cache contents can be gotten from the
> same file (optional, phase 2); incorrect pre-existing cache contents would be
> out of the scope of this.
