-Re: task jvm bootstrapping via distributed cache

I am guessing this is either a well-known problem or an edge case. In
any case, would it be a bad idea to designate predetermined output
E.g., DistributedCache.addCacheFileInto(uri, conf, outputPath) would
attempt to copy the cached file into the specified path resolving to a
task's local filesystem.
