I'm going to go ahead and post the version that sidesteps the catalog.

File be/src/scheduling/scheduler.cc:

PS2, Line 801:   uint32_t hash = 
HashUtil::Hash(&hdfs_file_split->full_path_hash,
             :       sizeof(hdfs_file_split->full_path_hash), 0);
> why hash the hash instead of just making the hash here be a uint32_t direct
Fixed this. Java hashCode() returns a signed integer and backend uses unsigned. 
I was punting on deciding the right place to cast.
