Example 3 with JavaHiveDecimalObjectInspector

use of org.apache.hadoop.hive.serde2.objectinspector.primitive.JavaHiveDecimalObjectInspector in project presto by prestodb.

the class AbstractTestParquetReader method testDecimalBackedByFixedLenByteArray.

@Test

    for (int precision = MAX_PRECISION_INT64 + 1; precision < MAX_PRECISION; precision++) {

        ContiguousSet<BigInteger> values = bigIntegersBetween(BigDecimal.valueOf(Math.pow(10, precision - 1)).toBigInteger(), BigDecimal.valueOf(Math.pow(10, precision)).toBigInteger());
