BF-7588

Test assertion failure due to not waiting for majority write to replicate to non-voting secondary. Fixed by SERVER-32774; however, SERVER-38120 indicates there is still an issue even after making the secondaries voting members of the replica set.

Setup

cd mongo
git checkout d729fe3fc6c43abd35e517aa2c796c491983329a
python2 buildscripts/scons.py     \
    -j$(nproc)                    \
    --disable-warnings-as-errors  \
    mongo mongod mongos
git checkout visemet/mongodb-rr-experiment
git am ../bf-7588/patches/0001-Remove-enableMajorityReadConcern-option-from-mongod.patch
git am ../bf-7588/patches/0002-Remove-transactionLifetimeLimitSeconds-server-parame.patch
git am ../bf-7588/patches/0003-Remove-wait-for-config.sessions-collection-creation.patch
git checkout d729fe3fc6c43abd35e517aa2c796c491983329a --                  \

git commit -m 'Use version of test from failing commit.'

rm -rf ~/.local/share/rr/*

    -j$(( $(nproc) / 3 ))                   \
    --repeatTests=1000                      \
    --continueOnFailure                     \
