[jira] [Created] (PARQUET-422) Fix a potential bug in MessageTypeParser where we ignore and overwrite the initial value of a method parameter

Liwei Lin created PARQUET-422:
---------------------------------

             Summary: Fix a potential bug in MessageTypeParser where we ignore and overwrite the initial value of a method parameter
                 Key: PARQUET-422
                 URL: https://issues.apache.org/jira/browse/PARQUET-422
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
    Affects Versions: 1.8.0, 1.8.1
            Reporter: Liwei Lin
            Priority: Minor
             Fix For: 1.9.0


In org.apache.parquet.schema.MessageTypeParser, for addGroupType() and addPrimitiveType(), the initial value of this parameter t is ignored, and t is overwritten here.

This often indicates a mistaken belief that the write to the parameter will be conveyed back to the caller.

This is a bug found by FindBugs™.
