> 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.
