LangYuanzh opened a new issue, #16532: URL: https://github.com/apache/dolphinscheduler/issues/16532
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened The version of dolphinscheduler is 3.1.7. The shell script is: ``` http_code=`curl -s -o result -w "%{http_code}" -X GET 'http://url of our service'` if [[ $http_code -eq 200 ]]; then echo "task execute success." else echo "task execute failed." cat result exit 1 fi param=`cat result` echo $param echo '${setValue(paramOut='${param}')}' ``` "paramOut" is set as a task param with OUT direct. The task is scheduled to run every minute and all was work well when the task is settled, but ArrayIndexOutOfBoundsException is throw after about ten hours and it's never recoverd. when run shell task with output param. And there is another problem: most of the time the param passing is wroking well, the next task node can obtain the correct param passed by the first shell task, but some time the next task obtain the param as blank and there is no error log. This situation happend occasionally. The task log: ``` [INFO] 2024-08-28 02:23:02.470 +0000 - task run command: sudo -u dolphinscheduler -E bash /data1/dolphinscheduler-data/exec/process/dolphinscheduler/11465962145888/14603302834144_23/281095/325874/281095_325874.command [INFO] 2024-08-28 02:23:02.471 +0000 - process start, process id is: 7742 [INFO] 2024-08-28 02:23:02.528 +0000 - process has exited. execute path:/data1/dolphinscheduler-data/exec/process/dolphinscheduler/11465962145888/14603302834144_23/281095/325874, processId:7742 ,exitStatusCode:0 ,processWaitForStatus:true ,processExitValue:0 [ERROR] 2024-08-28 02:23:02.530 +0000 - shell task error java.lang.ArrayIndexOutOfBoundsException: 1 at org.apache.dolphinscheduler.plugin.task.api.parameters.AbstractParameters.getMapByString(AbstractParameters.java:191) at org.apache.dolphinscheduler.plugin.task.api.parameters.AbstractParameters.dealOutParam(AbstractParameters.java:144) at org.apache.dolphinscheduler.plugin.task.shell.ShellTask.handle(ShellTask.java:99) at org.apache.dolphinscheduler.server.worker.runner.DefaultWorkerDelayTaskExecuteRunnable.executeTask(DefaultWorkerDelayTaskExecuteRunnable.java:49) at org.apache.dolphinscheduler.server.worker.runner.WorkerTaskExecuteRunnable.run(WorkerTaskExecuteRunnable.java:174) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.runInterruptibly(TrustedListenableFutureTask.java:131) at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:74) at com.google.common.util.concurrent.TrustedListenableFutureTask.run(TrustedListenableFutureTask.java:82) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748) [ERROR] 2024-08-28 02:23:02.531 +0000 - Task execute failed, due to meet an exception org.apache.dolphinscheduler.plugin.task.api.TaskException: Execute shell task error at org.apache.dolphinscheduler.plugin.task.shell.ShellTask.handle(ShellTask.java:108) at org.apache.dolphinscheduler.server.worker.runner.DefaultWorkerDelayTaskExecuteRunnable.executeTask(DefaultWorkerDelayTaskExecuteRunnable.java:49) at org.apache.dolphinscheduler.server.worker.runner.WorkerTaskExecuteRunnable.run(WorkerTaskExecuteRunnable.java:174) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at com.google.common.util.concurrent.TrustedListenableFutureTask$TrustedFutureInterruptibleTask.runInterruptibly(TrustedListenableFutureTask.java:131) at com.google.common.util.concurrent.InterruptibleTask.run(InterruptibleTask.java:74) at com.google.common.util.concurrent.TrustedListenableFutureTask.run(TrustedListenableFutureTask.java:82) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at org.apache.dolphinscheduler.plugin.task.api.parameters.AbstractParameters.getMapByString(AbstractParameters.java:191) at org.apache.dolphinscheduler.plugin.task.api.parameters.AbstractParameters.dealOutParam(AbstractParameters.java:144) at org.apache.dolphinscheduler.plugin.task.shell.ShellTask.handle(ShellTask.java:99) ... 9 common frames omitted [INFO] 2024-08-28 02:23:02.531 +0000 - -> task execute success. cat: result: No such file or directory [INFO] 2024-08-28 02:23:02.531 +0000 - FINALIZE_SESSION [INFO] 2024-08-28 02:23:02.531 +0000 - cancel process: 7742 [INFO] 2024-08-28 02:23:02.531 +0000 - Get a exception when execute the task, will send the task execute result to master, the current task execute result is TaskExecutionStatus{code=6, desc='failure'} [INFO] 2024-08-28 02:23:03.471 +0000 - FINALIZE_SESSION ``` ### What you expected to happen param passing working well ### How to reproduce as described above ### Anything else _No response_ ### Version 3.1.x ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
