László Bodor updated HIVE-29656:
--------------------------------
Description:
faced problems in negative tests qout in precommit CI
# export QTEST_LEAVE_FILES=true
# run qtest
# check files under
{{apache/hive/itests/qtest/target/qfile-results/clientnegative}}
# {{orig}} files are generated while running the tests, and they are
transformed by QOutProcessor to form the final result, which is then compared
to the golden
I compared the orig files with the final, and I saw strange stuff:
the masking should make the stack trace disappear, but apparently, not only the
stack trace disappeared...I'm afraid that the regex replace is not
deterministic, and can vary depending on my computer and CI environment

in the orig file, there is {{{color:#de350b}vertexName=Reducer 8 ...{color} ,
in the final file, it became {color:#00875a}Masked{color}}}
this can maybe cause qout difference in CI precommit which cannot be reproduced
locally, which is bad:
