thanks

i've got this error with workflow manager views

[#3]

and here my config views

[#4 · Accepted solution]

@mayki wogno From error logs, it looks like caused due to known bug https://issues.apache.org/jira/browse/AMBARI-19207 (This issue is faced across different views very intermittently).

In that case as a work around, please create a new workflow manager view instance and check if you are able to submit the workflow.

Another thing which I observed is, you need not have to provide 'WebHDFS authorization' property while creating the views. (This was needed only till ambari-2.2.2)

[#5]

Please follow these steps

This happened as the older Workflow Manager view's folder under work folder is not deleted properly.

@mayki wogno Please follow the following steps.

Step1: Stop Ambari server with command "ambari-server stop"

Step2: Go to the path "/var/lib/ambari-server/resources/views/work" and delete the work folder.

Step3: Now start Ambari with command "ambari-server start"

I hope, this should help you.

@vsairam, do you know if the original and the secondary errors mentioned above are both still applicable to WFM in Ambari 2.5.0.3 but with HDP 2.6? I'm guessing they are, but want to confirm. Thanks.

[#7]

Generally the update from older version to newer version(HDP 2.6) should do this process.

Im not sure of it as i havent tested this scenario.

I will update my findings soon.

But in the successful upgradation case, this error will be handled.
