[CI] RollupIT#testBig seems flaky #32032
Description
Failure today: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+6.x+intake/2071/console
Sadly doesn't reproduce locally:
REPRODUCE WITH: ./gradlew :x-pack:plugin:rollup:internalClusterTest \
-Dtests.seed=DC4DE8359D2EABD \
-Dtests.class=org.elasticsearch.xpack.rollup.RollupIT \
-Dtests.method="testBig" \
-Dtests.security.manager=true \
-Dtests.locale=zh-CN \
-Dtests.timezone=Asia/Srednekolymsk
But the error suggests a one-off count error that might appear just occasionally:
java.lang.AssertionError:
Expected: <89L>
but: was <90L>
