Subject Re: How to start a TaskManager and the Flink Query Interface from, Scala IDE (local run configuration)
Date Mon, 09 Mar 2015 19:57:54 GMT
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
