IMPALA-6070: Parallelize another bit of data load.
The two Kudu loads and Hive UDFs can all run in parallel. This
should shave about 4 minutes off of the data load. (Current
timings are 3.5, 4, and 0.6 minutes, see below.)
I've run dataload with this change many times.
Loading Kudu functional (logging to
/home/ubuntu/Impala/logs/data_loading/load-kudu.log)...
Loading workload 'functional-query' using exploration strategy 'core' in
table formats 'kudu/none/none' OK (Took: 3 min 29 sec)
