Hi @jinchengchenghh , I have been thinking if the code can be simplified to
ease maintenance.
Would you please have a check about the following example code to pretty
print a row iterator with much less code than `ToStringUtil`:
```scala
test("UnsafeRow to string 2") {
val util = ToStringUtil(Option.apply(SQLConf.get.sessionLocalTimeZone))
val row1 =
InternalRow.apply(UTF8String.fromString("hello"),
UTF8String.fromString("world"), 123)
val rowWithNull = InternalRow.apply(null, null, 4)
val row2 = UnsafeProjection
.create(Array[DataType](StringType, StringType, IntegerType))
.apply(rowWithNull)
val it = List(row1, row2, row1, row1, row2).toIterator
val struct = new StructType().add("a", StringType).add("b",
StringType).add("c", IntegerType)
val encoder = RowEncoder(struct).resolveAndBind()
val deserializer = encoder.createDeserializer()
it.map(deserializer).foreach(r => println(r.mkString("|")))
}
```
