---------------------------------------------
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.
