---------------------------------------
Thanks, I'll go ahead and get a patch ready.
> Beeline set var=value not carrying over to queries
> --------------------------------------------------
>
> Key: HIVE-10656
> URL: https://issues.apache.org/jira/browse/HIVE-10656
> Project: Hive
> Issue Type: Bug
> Reporter: Reuben Kuhnert
> Priority: Minor
>
> After performing a {{set name=value}} I would expect that the variable name
> would carry over to all locations within the session. It appears to work when
> querying the value via {{set;}}, but not when trying to do actual sql
> statements.
> Example:
> {code}
> 0: jdbc:hive2://localhost:10000> set foo;
> +----------+--+
> | set |
> +----------+--+
> | foo=bar |
> +----------+--+
> 1 row selected (0.932 seconds)
> 0: jdbc:hive2://localhost:10000> select * from ${foo};
> Error: Error while compiling statement: FAILED: SemanticException [Error
> 10001]: Line 1:14 Table not found 'bar' (state=42S02,code=10001)
> 0: jdbc:hive2://localhost:10000> show tables;
> +------------+--+
> | tab_name |
> +------------+--+
> | my |
> | purchases |
> +------------+--+
> 2 rows selected (0.437 seconds)
> 0: jdbc:hive2://localhost:10000> set foo=my;
> No rows affected (0.017 seconds)
> 0: jdbc:hive2://localhost:10000> set foo;
> +---------+--+
> | set |
> +---------+--+
> | foo=my |
> +---------+--+
> 1 row selected (0.02 seconds)
> 0: jdbc:hive2://localhost:10000> select * from ${foo};
> select * from ${foo};
> Error: Error while compiling statement: FAILED: SemanticException [Error
> 10001]: Line 1:14 Table not found 'bar' (state=42S02,code=10001)
> {code}
