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

             Summary: Hive is unable to read Parquet int32 annotated with decimal
                 Key: HIVE-21987
                 URL: https://issues.apache.org/jira/browse/HIVE-21987
             Project: Hive
          Issue Type: Bug
            Reporter: Nandor Kollar
         Attachments: part-00000-d6ee992d-ef56-4384-8855-5a170d3e3660-c000.snappy.parquet

When I tried to read a Parquet file from a Hive (with Tez execution engine) table with a small decimal column, I got the following exception:
{code}
Caused by: java.lang.UnsupportedOperationException: org.apache.hadoop.hive.ql.io.parquet.convert.ETypeConverter$8$1
	at org.apache.parquet.io.api.PrimitiveConverter.addInt(PrimitiveConverter.java:98)
	at org.apache.parquet.column.impl.ColumnReaderImpl$2$3.writeValue(ColumnReaderImpl.java:248)
	at org.apache.parquet.column.impl.ColumnReaderImpl.writeCurrentValueToConverter(ColumnReaderImpl.java:367)
	at org.apache.parquet.io.RecordReaderImplementation.read(RecordReaderImplementation.java:406)
	at org.apache.parquet.hadoop.InternalParquetRecordReader.nextKeyValue(InternalParquetRecordReader.java:226)
	... 28 more
{code}

Steps to reproduce:
- Create a Hive table with a single decimal(4, 2) column
- Create a Parquet file with int32 column annotated with decimal(4, 2) logical type, put it into the previously created table location (or use the attached parquet file)
- Execute a {{select *}} on this table
