> 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
