> Key: SPARK-5456
> URL: https://issues.apache.org/jira/browse/SPARK-5456
> Project: Spark
> Issue Type: Bug
> Components: SQL

> Not quite able to figure this out but here is a junit test to reproduce this,
> in JavaAPISuite.java
> {code:title=DecimalBug.java}
> @Test
> public void decimalQueryTest() {
> List<Row> decimalTable = new ArrayList<Row>();
> decimalTable.add(RowFactory.create(new BigDecimal("1"), new
> BigDecimal("2")));
> decimalTable.add(RowFactory.create(new BigDecimal("3"), new
> BigDecimal("4")));
> JavaRDD<Row> rows = sc.parallelize(decimalTable);
> List<StructField> fields = new ArrayList<StructField>(7);
> fields.add(DataTypes.createStructField("a",
> DataTypes.createDecimalType(), true));
> fields.add(DataTypes.createStructField("b",
> DataTypes.createDecimalType(), true));
> sqlContext.applySchema(rows.rdd(),
> DataTypes.createStructType(fields)).registerTempTable("foo");
> Assert.assertEquals(sqlContext.sql("select * from foo where a >
> 0").collectAsList(), decimalTable);
> }
