Summary: set eventtime from source with timestampsFromField
funcation at flink 1.10 error
Key: FLINK-17186
URL: https://issues.apache.org/jira/browse/FLINK-17186
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 1.10.0
Reporter: jiefeng zheng
the stream schema is: the stream schema is: row_timenumber
the code is:new Schema().field("row_time", Types.SQL_TIMESTAMP)
.rowtime(new Rowtime().timestampsFromField("row_time")
.watermarksPeriodicBounded(1000))
.field("number", Types.INT) its not work ,who can help? the error
show as belowjava.lang.NullPointerException at
