[jira] [Created] (DRILL-8249) NullPointerException is thrown when trying select from parquet file

Artem Trush created DRILL-8249:
----------------------------------

             Summary: NullPointerException is thrown when trying select from parquet file
                 Key: DRILL-8249
                 URL: https://issues.apache.org/jira/browse/DRILL-8249
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Parquet
    Affects Versions: 1.20.1, 1.20.0
            Reporter: Artem Trush
            Assignee: Artem Trush
             Fix For: 1.20.2
         Attachments: nation.dict.parquet

After one of the recent fix - [DRILL-1282|[https://github.com/apache/drill/pull/2338]] drill started to throw npe. Issue is related to drill 1.20 and above.

Simple {{SELECT * FROM}}  from {{nation.dict.parquet}} file. Attached it.

Were investigated that the code [here|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/columnreaders/VarLenColumnBulkInput.java#L318L341] is not working as expected. Before DRILL-1282 these code lines were not used for reading this file (or I guess any file).
