Example 96 with DecimalColumnVector

use of org.apache.hadoop.hive.ql.exec.vector.DecimalColumnVector in project hive by apache.

the class TestVectorTypeCasts method getBatchLongDecimalPrec5Scale2.

 * This batch has output decimal column precision 5 and scale 2.
 * The goal is to allow testing of input long values that, when
 * converted to decimal, will not fit in the given precision.
 * Then it will be possible to check that the results are NULL.
