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

             Summary: Support for Parquet Binary DecimalType in VectorizedColumnReader
                 Key: SPARK-23388
                 URL: https://issues.apache.org/jira/browse/SPARK-23388
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: James Thompson


The following commit to spark removed support for decimal binary types: [https://github.com/apache/spark/commit/9c29c557635caf739fde942f53255273aac0d7b1#diff-7bdf5fd0ce0b1ccbf4ecf083611976e6R428]

As per the parquet spec, decimal can be used to annotate binary types, so support should be re-added: [https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#decimal]
