---------------------------------------

Hi, [~panbingkun]. For new feature or improvement, we use the version of master branch at `Affected Version` field because new feature and improvements cannot affect existing releases due to Apache Spark backport policy. As of today, the version of master branch is `3.4.0-SNAPSHOT`. I updated your JIRA's Affected Version to 3.4.0 from 3.3.0.
