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

Yep, it works with the newest build. Was just a glitch in the matrix :)

Thanks again!

Mh. Thats weird. It looks like your JobManager is being started in the cluster mode.
Can you pull the latest changes from master? (We've worked quite a bit on exactly the startup and logging behavior of the JM / TM). 
Usually, there should be a message like:
21:10:22,652 INFO org.apache.flink.runtime.jobmanager.JobManager - Starting JobManager actor 21:10:22,660 INFO org.apache.flink.runtime.blob.BlobServer - Created BLOB server storage directory /tmp/blobStore-f0f79652-bf0a-4078-9382-343bab674742 21:10:22,661 INFO org.apache.flink.runtime.blob.BlobServer - Started BLOB server at 0.0.0.0:39344 <http://0.0.0.0:39344> - max concurrent requests: 50 - max backlog: 1000 21:10:22,671 INFO org.apache.flink.runtime.jobmanager.JobManager - Starting embedded TaskManager for JobManager's LOCAL execution mode

    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

    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!
