----------------------------
Summary: source:canal-cdc , sink:upsert-kafka, print "select *
from sinkTable", throw NullException
Key: FLINK-21889
URL: https://issues.apache.org/jira/browse/FLINK-21889
Project: Flink
Issue Type: Bug
Components: Connectors / Kafka
Affects Versions: 1.12.1
Environment: flink 1.12.1
Reporter: Carl
Fix For: 1.12.3
Attachments: JIRA.java, JIRA.txt
sourceTable:canal-cdc , sinkTable:upsert-kafka, print the result of
executesql("select * from sinkTable"), or print the result of RetractStream for
sinkTable program will throw a NullException
if print the result of executesql("select * from sourceTable") or use some
other operator to trigger the program，it will not throw the NullException。
