-----------------------------------
Summary: NullPointerException
LogicalCorrelateToJoinFromTemporalTableFunctionRule.scala:157
Key: FLINK-21345
URL: https://issues.apache.org/jira/browse/FLINK-21345
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.12.1
Environment: Planner: BlinkPlanner
Flink Version: 1.12.1_2.11
Java Version: 1.8
OS: mac os
Reporter: lynn1.zhang
First Step: Create 2 Source Tables as below:
{code:java}
CREATE TABLE test_streaming(
vid BIGINT,
ts BIGINT,
proc AS proctime()
) WITH (
'connector' = 'kafka',
'topic' = 'test-streaming',
'properties.bootstrap.servers' = '127.0.0.1:9092',
'scan.startup.mode' = 'latest-offset',
'format' = 'json'
);
CREATE TABLE test_streaming2(
vid BIGINT,
ts BIGINT,
proc AS proctime()
) WITH (
'connector' = 'kafka',
'topic' = 'test-streaming2',
'properties.bootstrap.servers' = '127.0.0.1:9092',
'scan.startup.mode' = 'latest-offset',
'format' = 'json'
);
{code}
Second Step: Create a TEMPORARY Table Function, function name:dim, key:vid,
timestamp:proctime()
Third Step, test_streaming union all test_streaming2 join dim like below:
{code:java}
SELECT r.vid,d.name,timestamp_from_long(r.ts)
FROM (
SELECT * FROM test_streaming UNION ALL SELECT * FROM test_streaming2
) AS r,
LATERAL TABLE (dim(r.proc)) AS d
WHERE r.vid = d.vid;
{code}
Exception Detail:(if not union all, the program run ok)
{code:java}
Exception in thread "main" java.lang.NullPointerException
