Hi Juan, I searched in the repo, and only found two modules contains `org.antlr`: 1, flink-sql-client 2, flink-connector-hive But they exist only because we need to exclude them from 'hive-exec' dependency.
BTW, where did you find flink importing `org.antlr` ? Juan Pan <panj...@apache.org> 于2019年12月29日周日 下午3:07写道： > Hi folks, > > Excuse me for this help-seeking email.
