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

             Summary: Avoid expensive AST tree conversion to String for 
expressions in WHERE clause in CBO
                 Key: HIVE-11813
                 URL: https://issues.apache.org/jira/browse/HIVE-11813
             Project: Hive
          Issue Type: Bug
          Components: CBO
    Affects Versions: 1.3.0, 2.0.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


We use the AST tree String representation of a condition in the WHERE clause to 
identify its column in the RowResolver. This can lead to OOM Exceptions when 
the condition is very large.
