IMPALA-13058: Init first_arrival_time_ and completion_time_ with -1
Impala run over ARM machine shows 'arch_sys_counter' clock source being
used rather than more precise 'tsc'. This cause
MonotonicStopwatch::Now() to use 'CLOCK_MONOTONIC_COARSE' rather than
'CLOCK_MONOTONIC'. This is what printed near the beginning of impalad
log:
I0506 13:49:15.429359 355337 init.cc:600] OS distribution: Red Hat Enterprise
Linux 8.8 (Ootpa)
OS version: Linux version 4.18.0-477.15.1.el8_8.aarch64 ...
Clock: clocksource: 'arch_sys_counter', clockid_t: CLOCK_MONOTONIC_COARSE
This difference in clock source causes test failure in
test_runtime_filters.py::TestRuntimeFilters::test_basic_filters. This
patch fixes the issue by initializing first_arrival_time_ and
completion_time_ fields of Coordinator::FilterState with -1 and accept 0
as valid value for those fields.
query_events_ initialization and start are also moved to the beginning
of ClientRequestState's contructor.
Testing:
- Tweak row_regex pattern in runtime_filters.test.
- Loop and pass test_runtime_filters.py in exhaustive mode 3 times
in ARM machine.
