[jira] [Created] (PARQUET-1472) Dictionary filter fails on FIXED_LEN_BYTE_ARRAY

Gabor Szadovszky created PARQUET-1472:
-----------------------------------------

             Summary: Dictionary filter fails on FIXED_LEN_BYTE_ARRAY
                 Key: PARQUET-1472
                 URL: https://issues.apache.org/jira/browse/PARQUET-1472
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
            Reporter: Gabor Szadovszky
            Assignee: Gabor Szadovszky


DictonaryFilter does not handle FIXED_LEN_BYTE_ARRAY. Moreover, [DictionaryFilter.expandFilter(ColumnChunkMetaData)|https://github.com/apache/parquet-mr/blob/dc61e510126aaa1a95a46fe39bf1529f394147e9/parquet-hadoop/src/main/java/org/apache/parquet/filter2/dictionarylevel/DictionaryFilter.java#L78] returns an empty map instead of null therefore the row-group might be dropped as the value seems to not being in the dictionary.
