Use of Add "New Application" in Streaming Applications Manager - SAM in Hortonworks Data Flow (HDF-3), gives ERROR - Cannot read property "topologyComponentUISpecification" of undefined !!

Use of Add "New Application" in Streaming Applications Manager - SAM in Hortonworks Data Flow (HDF-3), gives ERROR - Cannot read property "topologyComponentUISpecification" of undefined !!

Explorer

When I click on NEW APPLICATION option under "My Application" in S.A.M, to add/create a NEW application, SAM displays the ERROR - "Cannot read property 'TopologyComponentUISpecification' of undefined" !!!

PLEASE NOTE:

(a) I have previously created - a valid SERVICE POOL and ENVIRONMENT in SAM, successfully, for use by the 'New Application' builder.

(b) How can I resolve the above ERROR, to continue to ADD a NEW APPLICATION (using the 'New Application' function) in SAM ??

@Leonard Edwin can you make sure you ran /usr/hdf/current/streamline/bootstrap/bootstrap.sh . Make sure the server is up and running.

Hi Shriharsha, thanks for the advice to run the 'bootstrap.sh' script ... It resolved the issue and I was able to add/create the application.

However, when I dragged a KAFKA source tile component unto the Application Builder canvas - and double clicked on it to configure/specify the mandatory argument 'KAFKA TOPIC*'; on selecting the correct topic from the dropdown list - the error 'SCHEMA NOT FOUND' was displayed by the application builder service.

How can I resolve this second error ??

Thank You :)

so the schema name and the topic name need to be same, thus it shows it in the drop down.
