[~niuyulin] [~zcq_rambo] I just realized that we have 2 PRs: one for master and
another for branch-2.2, both from different authors.
Usually, only Jira assignee creates PR and we create PR for just master branch
as long as the patch is not huge and patch is not significantly different
across multiple release branches. For now it's fine, will merge both PRs after
some time. Also, master PR has test, so let me include that for branch-2.2
commit also.
Thanks to both of you for finding and fixing this nice bug.

When we use HFileBlockIndex#rootBlockContainingKey() with a cell created by
