In conf.yaml file, replace the setting ‘env.java.opts: "-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005" ‘ as mentioned in the link with the below setting
env.java.opts.taskmanager: "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005" Regards, Teena From: Tharmakulasingham Inthirakumaaran <inthira...@cse.mrt.ac.lk> Sent: 22 June 2018 17:10 To: user@flink.apache.org Subject: Remote Debugging Flink Hi, I am new to flink and trying to remote debug flink cluster. I followed the instructions mentioned in the link[1] but when I do that I could not run the SocketWindowWordCount example(any example at all). The main problem is there are no task slots or task manager initiated. Then I followed the link[2] and set the java.opts for task manager but still don't have any task slots initiated. I am currently running flink instance in the local machine. I checked the Dispatcher’s web frontend to see whether slots have initiated or not. The error I am getting at the terminal is like: Caused by: org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: Could not allocate all requires slots within timeout of 300000 ms. Slots required: 2, slots allocated: 0 at org.apache.flink.runtime.executiongraph.ExecutionGraph.lambda$scheduleEager$3(ExecutionGraph.java:984) at java.util.concurrent.CompletableFuture.uniExceptionally(CompletableFuture.java:870)... Can you please suggest the correct way to do this?
