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

             Summary: Hive dialect can't get value for the variables set by  set command
                 Key: FLINK-29191
                 URL: https://issues.apache.org/jira/browse/FLINK-29191
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Hive
    Affects Versions: 1.16.0
            Reporter: luoyuxia
             Fix For: 1.16.0


When using Hive dialect, we can use 
{code:java}
set k1=v1;
{code}
to set variable to Flink's table config.

But if we want the get the value for `k1` by using 
{code:java}
set k1;
{code}
we will get nothing.

The reason is Hive dialect won't lookup the vairable in Flink's table config.

To fix it, we also need to lookup in link's table config.
