to look at the new patch set (#4).

......................................................................
IMPALA-12268: Fix possible blocking when use java.lang.Process.
When use java.lang.Process, because some native platforms only provide
limited buffer size for standard input and output streams, failure to
promptly write the input stream or read the output stream of the
subprocess may cause the subprocess to block, or even deadlock.
This patch provides a class 'InputStreamGobbler' to consume the streams
produced by subprocess asynchronously.
Testing:
- add a FE test 'InputStreamGobblerTest'.
- run core job.
