I dig into another issue[
ZOOKEEPER-3023](https://issues.apache.org/jira/browse/ZOOKEEPER-3023) which may
be the same issue or the timeout `50ms` is too short to get updated data.
When Jenkins does regression,the disk is heavy and busy.some state/data
can't sync from leader to learner ,which may be a salient cause for flaky test.
