Hi,
I was trying out examples given here
<
https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/dev/table/data_stream_api/#examples-for-fromdatastream>
to convert Datastream to Table and one of the example gives out error.
My code is as follows :
/StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
DataStream<User> dataStream =
env.fromElements(
new User("Alice", 4, Instant.ofEpochMilli(1000)),
new User("Bob", 6, Instant.ofEpochMilli(1001)),
new User("Alice", 10, Instant.ofEpochMilli(1002)))
.assignTimestampsAndWatermarks(WatermarkStrategy.<User>forBoundedOutOfOrderness(Duration.ofSeconds(60)));
StreamTableEnvironment tableEnv =
StreamTableEnvironment.create(env);
Table table =
tableEnv.fromDataStream(
dataStream,
Schema.newBuilder()
.column("event_time", "TIMESTAMP(3)")
.column("name", "STRING")
.column("score", "INT")
.watermark("event_time",
"SOURCE_WATERMARK()")
.build());
table.printSchema();
table.select($("*")).execute().print();/
and the error I got is :
/Caused by: org.codehaus.commons.compiler.CompileException: Line 13, Column
103: Cannot cast "java.time.Instant" to "java.time.LocalDateTime"
at org.codehaus.janino.UnitCompiler.compileError(UnitCompiler.java:12211)

at org.codehaus.janino.Java$Cast.accept(Java.java:4898)
at org.codehaus.janino.UnitCompiler.compileGet(UnitCompiler.java:4396)/
Can somebody help with this ?
