                 URL: https://issues.apache.org/jira/browse/FLINK-20809

    Affects Versions: 1.12.0
            Reporter: Jun Zhang
             Fix For: 1.13.0


when I use flink sql to query hive table , like this 
{code:java}
// select * from hive_table where id = 1 limit 1
{code}
 
when the sql contain query conditions in where clause, I found that the limit push down is invalid.

I look up the comment on source code , I think it is should be push down , is it a bug ?
