Subclasses of VectorPTFEvaluatorCount in org.apache.hadoop.hive.ql.exec.vector.ptf

Modifier and Type	Class and Description
class	VectorPTFEvaluatorBytesCountDistinct Bytes (String) implementation for VectorPTFEvaluatorCountDistinct.
class	VectorPTFEvaluatorCountDistinct This class evaluates count(column) for a PTF group where a distinct keyword is applied to the partitioning column itself, e.g.: SELECT txt1, txt2, count(distinct txt1) over(partition by txt1) as n, count(distinct txt2) over(partition by txt2) as m FROM example; In this case, the framework is still supposed to ensure sorting on the key (let's say txt1 for the first Reducer stage), but the original VectorPTFEvaluatorCount is not aware that a distinct keyword was applied to the key column.
class	VectorPTFEvaluatorDecimalCountDistinct Double implementation for VectorPTFEvaluatorCountDistinct.
class	VectorPTFEvaluatorDoubleCountDistinct Double implementation for VectorPTFEvaluatorCountDistinct.
class	VectorPTFEvaluatorLongCountDistinct Long implementation for VectorPTFEvaluatorCountDistinct.
class	VectorPTFEvaluatorTimestampCountDistinct Timestamp implementation for VectorPTFEvaluatorCountDistinct.
