----------------------------------

Agree with (1) through (4). (5) would only work if a) all URIs had different
base names or b) we could simply use whole URIs as cache file names. But we
cannot assume either to be the case.

What's wrong with (b)? We probably need to encode the URI to get the filename
if we want to avoid colons and slashes. Is that what you meant?

> The slave should be smarter about how it handles pulling down executors. In
> our environment, executors rarely change but the slave will always pull it
> down from regardless HDFS. This puts undue stress on our HDFS clusters, and
> is not resilient to reduced HDFS availability.
