             Summary: A memory leak is observed when exact case is not specified for a column in a filter condition
                 Key: DRILL-5121
                 URL: https://issues.apache.org/jira/browse/DRILL-5121
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Relational Operators
    Affects Versions: 1.8.0, 1.6.0
            Reporter: Karthikeyan Manivannan
            Assignee: Karthikeyan Manivannan
             Fix For: Future


When the query SELECT XYZ from dfs.`/tmp/foo' where xYZ like "abc", is executed on a setup where /tmp/foo has 2 Parquet files, 1.parquet and 2.parquet, where 1.parquet has the column XYZ but 2.parquet does not, then there is a memory leak. 

This seems to happen because xYZ seem to be treated as a new column.
