i wanna try fix this |

@davidyuan1223 thanks~ |
|
my suggestion code update is make the sessionConf `kyuubi.session.engine.flink.max.rows=10000', what do you think? |

… the max rows setting ### _Why are the changes needed?_ #### 1. know about this pr When we execute flink(1.17+) test case, it may throw exception when the test case is `show/stop job`, the exception desc like this ``` - execute statement - show/stop jobs *** FAILED *** org.apache.kyuubi.jdbc.hive.KyuubiSQLException: Error operating ExecuteStatement: org.apache.flink.table.gateway.service.utils.SqlExecutionException: Could not stop job 4dece26857fab91d63fad1abd8c6bdd0 with savepoint for operation 9ed8247a-b7bd-4004-875b-61ba654ab3dd. at org.apache.flink.table.gateway.service.operation.OperationExecutor.lambda$callStopJobOperation$11(OperationExecutor.java:628) at org.apache.flink.table.gateway.service.operation.OperationExecutor.runClusterAction(OperationExecutor.java:716) at org.apache.flink.table.gateway.service.operation.OperationExecutor.callStopJobOperation(OperationExecutor.java:601) at org.apache.flink.table.gateway.service.operation.OperationExecutor.executeOperation(OperationExecutor.java:434) at org.apache.flink.table.gateway.service.operation.OperationExecutor.executeStatement(OperationExecutor.java:195) at org.apache.kyuubi.engine.flink.operation.ExecuteStatement.executeStatement(ExecuteStatement.scala:64) at org.apache.kyuubi.engine.flink.operation.ExecuteStatement.runInternal(ExecuteStatement.scala:56) at org.apache.kyuubi.operation.AbstractOperation.run(AbstractOperation.scala:171) at org.apache.kyuubi.session.AbstractSession.runOperation(AbstractSession.scala:101) at org.apache.kyuubi.session.AbstractSession.$anonfun$executeStatement$1(AbstractSession.scala:131) at org.apache.kyuubi.session.AbstractSession.withAcquireRelease(AbstractSession.scala:82) at org.apache.kyuubi.session.AbstractSession.executeStatement(AbstractSession.scala:128) at org.apache.kyuubi.service.AbstractBackendService.executeStatement(AbstractBackendService.scala:67) at org.apache.kyuubi.service.TFrontendService.ExecuteStatement(TFrontendService.scala:252) at org.apache.kyuubi.shade.org.apache.hive.service.rpc.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1557) at org.apache.kyuubi.shade.org.apache.hive.service.rpc.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1542) at org.apache.kyuubi.shade.org.apache.thrift.ProcessFunction.process(ProcessFunction.java:39) at org.apache.kyuubi.shade.org.apache.thrift.TBaseProcessor.process(TBaseProcessor.java:39) at org.apache.kyuubi.service.authentication.TSetIpAddressProcessor.process(TSetIpAddressProcessor.scala:36) at org.apache.kyuubi.shade.org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:286) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1[149](https://github.com/apache/kyuubi/actions/runs/6649714451/job/18068699087?pr=5501#step:8:150)) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:750) Caused by: java.util.concurrent.ExecutionException: java.util.concurrent.CompletionException: java.util.concurrent.CompletionException: org.apache.flink.runtime.checkpoint.CheckpointException: Checkpoint triggering task Source: tbl_a[6] -> Sink: tbl_b[7] (1/1) of job 4dece26857fab91d63fad1abd8c6bdd0 is not being executed at the moment.

If we want know the reason about the exception, we need to understand the process of flink executing stop job, the process line like this code space show(it's source is our bad test case, we can use this test case to solve similar problems) ``` 1. sql 1.1 create table tbl_a (a int) with ('connector' = 'datagen','rows-per-second'='10') 1.2 create table tbl_b (a int) with ('connector' = 'blackhole') 1.3 insert into tbl_b select * from tbl_a 2. start job: it will get 2 tasks abount source sink 3. show job: we can get job info 4. stop job(the main error): 4.1 stop job need checkpoint 4.2 start checkpoint, it need all task state is running 4.3 checkpoint can not get all task state is running, then throw the exception ``` Actually, in a normal process, it should not throw the exception, if this happens to your job, please check your kyuubi conf `kyuubi.session.engine.flink.max.rows`, it's default value is 1000000. But in the test case, we only the the conf's value is 10. It's the reason to make the error, this conf makes when we execute a stream query, it will cancel the when the limit is reached. Because flink's datagen is a streamconnector, so we can imagine, when we execute those sql, because our conf, it will make the sink task be canceled because the query reached 10. So when we execute stop job, flink checkpoint cannot get the tasks about this job is all in running state, then flink throw this exception. #### 3. how can we solve this problem? When your job makes the same exception, please make sure your kyuubi conf `kyuubi.session.engine.flink.max.rows`'s value can it meet your streaming query needs? Then changes the conf's value. close #5531 ### _How was this patch tested?_ - [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [x] [Run test](https://kyuubi.readthedocs.io/en/master/contributing/code/testing.html#running-tests) locally before make a pull request ### _Was this patch authored or co-authored using generative AI tooling?_ No Closes #5549 from davidyuan1223/fix_flink_test_bug.
