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

             Summary: Predicate push down fails in case of schema is evolved (alias)
                 Key: PARQUET-794
                 URL: https://issues.apache.org/jira/browse/PARQUET-794
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-avro
    Affects Versions: 1.8.0
            Reporter: Sunil


I am trying to read 2 parquet files  in which one file has evolved schema by renaming a column say B from A. Error is thrown when I read them through latest schema and predicate on column B (say B > 10) 

Caused by: java.lang.IllegalArgumentException: Column B does not exist.
	at parquet.filter.ColumnRecordFilter$1.bind(ColumnRecordFilter.java:54)
