> 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.
