[jira] [Commented] (IMPALA-15045) TestHS2.test_long_polling_full_sleep fails on UBSAN ARM builds

IMPALA-15045: Deflake TestHS2.test_long_polling_full_sleep
TestHS2.test_long_polling_full_sleep has a check of the
timing of a single call to GetOperationStatus. On some
slow build types (particularly UBSAN on ARM), the call is
taking longer than the expected 100ms. The highest time seen
in the failing tests is a little above 200ms. To avoid this
flakiness, this increases the threshold to 250ms for slow
build types. This is still well short of the runtime of
the query.
Testing:
- Ran locally
