IMPALA-13584: Add option to shows num row report in impala-shell
In beeswax all statements with the exception of USE print
'Fetched X row(s) in Ys', while in HS2 some statements (REFRESH,
INVALIDATE) metadata does not print it. While these statements always
return 0 rows, the amount of time spent with the statement can be
useful.
This patch modifies add impala-shell to let it print elapsed time for
that query, even if query is not expected to return result metadata.
Added --beeswax_compat_num_rows option in impala-shell. It default to
False. If this option is set (True), 'Fetched 0 row(s) in' will be
printed for all Impala protocol, just like beeswax. One exception for
this is USE query, which will remain silent.
Testing:
- Added test_beeswax_compat_num_rows in test_shell_interactive.py.
- Pass test_shell_interactive.py.
