    Description

      ConversionTreeReaders does not seem to handle Decimal64 column vectors. Hive creates VRB with Decimal64ColumnVectors when possible which gets passed down to ConversionTreeReaders which results in following ClassCastException

      Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.ql.exec.vector.Decimal64ColumnVector cannot be cast to org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector
