Re: How to start a TaskManager and the Flink Query Interface from, Scala IDE (local run configuration)

Mon, 09 Mar 2015 13:05:14 -0700 

Hi,
thank you for your answer. The JobManager web interface aka Flink Dashboard is accessible. 


I see, but there is a *ProgramInvocationException* thrown and the job 
fails when I submit the WordCount job through the CLI:



Caused by: 
org.apache.flink.runtime.jobmanager.scheduler.*NoResourceAvailableException*: 
Not enough free slots available to run the job. You can decrease the 
operator parallelism or increase the number of slots per TaskManager in 
the configuration. Task to schedule: < Attempt #0 (CHAIN DataSource (at 
getTextDataSet(WordCount.java:141) 
(org.apache.flink.api.java.io.TextInputFormat)) -> FlatMap (FlatMap at 
main(WordCount.java:67)) -> Combine(SUM(1), at main(WordCount.java:67) 
(1/1)) @ (unassigned) - [SCHEDULED] > with groupID <

35280a6b7eee8c72eb8e3f4f7975c680] >. Resources available to scheduler: 
Number of instances=0, total number of slots=0, available slots=0



I've then tried adding the following to the flink-conf.yaml 
configuration. This didn't solve the problem though.


taskmanager.numberOfTaskSlots: 4

Best regards,
Mihail

Hi,

this looks actually quite good.
Is the JobManager web interface accessible on port 8081 ?

With the exec mode set " --executionMode LOCAL" there is no explicit 
start of a TaskManager required. Its running in the same JVM as the 
JobManager.



The Flink Query Interface needs to be started using another main 
class: org.apache.flink.client.WebFrontend.


Let me know if you need more help!

    Hey Robert,

    the logging level was INFO and I didn't get any errors.
    After I switched to DEBUG I get the following output:
