TimestampedFileInputSplit cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType.
项目场景：flink-1.12.0版本
提示：这里简述项目相关背景：转换算子测试

问题描述：
错误提示：TimestampedFileInputSplit cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType.
Please read the Flink documentation on “Data Types & Serialization” for details of the effect on performance.
TimestampedFileInputSplit does not contain a setter for field modificationTime
 public static void main(String[] args) throws Exception {

final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
env.setParallelism(1);
DataStreamSource<String> stringDataStreamSource = env.readTextFile("sensor.txt");
DataStream<SensorReading> mapDataStream = stringDataStreamSource.map(line -> {
String[] fields = line.split(",");
if (fields.length>0){
return new SensorReading(fields[0],
new Long(fields[1]),
new Double(fields[2]));
}
return new SensorReading();
});

KeyedStream<SensorReading, String> keyedStream = mapDataStream.keyBy(sensorReading -> sensorReading.getId());
DataStream<SensorReading> maxBy = keyedStream.maxBy("temperature");
maxBy.print("sensor");
env.execute("sensor");

managed-schema中Valid attributes for fields的中文翻译
managed-schema文件的命名规则
字段名由字母数字下划线组成，且不能以数字开头。两端为下划线的字段为保留字段，如(version)。
<!-- Valid attributes for fields:
name: mandatory - the name for the field
type: mandatory - the name of a field type from the
fieldTypes section
indexed: true if this field should be indexed (searchable or sortable)
stored: true if this field should be retrievable
docValues: true if this field should have doc values. Doc Values is
recommended (required, if you are using *Point fields) for faceting,
grouping, sorting and function queries. Doc Values will make the index
faster to load, more NRT-friendly and more memory-efficient.
They are currently only supported by StrField, UUIDField, all
*PointFields, and depending on the field type, they might require
the field to be single-valued, be required or have a default value
(check the documentation of the field type you're interested in for
more information)
multiValued: true if this field may contain multiple values per document
omitNorms: (expert) set to true to omit the norms associated with
this field (this disables length normalization and index-time
boosting for the field, and saves some memory).  Only full-text
fields or fields that need an index-time boost need norms.
Norms are omitted for primitive (non-analyzed) types by default.
termVectors: [false] set to true to store the term vector for a
given field.
When using MoreLikeThis, fields used for similarity should be
stored for best performance.
termPositions: Store position information with the term vector.
This will increase storage costs.
termOffsets: Store offset information with the term vector. This
will increase storage costs.
required: The field is required.  It will throw an error if the
value does not exist
default: a value that should be used if no value is specified
when adding a document.

翻译内容
<!-- 字段的有效属性:
name: 字段名 （必须属性）
type: <types>中定义的字段类型 （必须属性）
indexed: 如果字段需要被索引（用于搜索或排序），值设置为true
stored: 如果字段内容需要被返回，值设置为true；
如果返回的字段在文档（documents）里没数据，则不会返回，即没有对应数据的字段不会被返回。
docValues: 如果这个字段应该有文档值（doc values），设置为true。
文档值在门面搜索，分组，排序和函数查询中会非常有用。虽然不是必须的，而且会导致生成
索引变大变慢，但这样设置会使索引加载更快，NRT更加友好，内存使用效率更高。
然而也有一些使用限制：目前仅支持StrField, UUIDField和所有 Trie*Fields,
并且依赖字段类型, 可能要求字段为单值（single-valued）的,必须的或者有默认值。
multiValued: 如果这个字段在每个文档中可能包含多个值，设置为true
termVectors: [false] 设置为true后，会保存所给字段的相关向量（vector）
当使用MoreLikeThis时, 用于相似度判断的字段需要设置为stored来达到最佳性能.
termPositions: 保存和向量相关的位置信息，会增加存储开销
termOffsets: 保存 offset 和向量相关的信息，会增加存储开销
required: 字段必须有值，否则会抛异常
default: 在增加文档时，可以根据需要为字段设置一个默认值，防止为空
