Failed to get scheduler location from state manager Heron Tutorial

Question

I'm working through the heron tutorial found here: https://apache.github.io/incubator-heron/docs/getting-started/'

I didn't get very far before I encountered this error:

$: heron activate local WindowedWordCountTopology

[2019-02-01 15:55:11 +0000] [INFO]: Using cluster definition in /home/<my-user>/.heron/conf/local
[2019-02-01 15:55:11 +0000] [ERROR]: Failed to get scheduler location from state manager
[2019-02-01 15:55:11 +0000] [ERROR]: Failed to activate topology: WindowedWordCountTopology

I'm very new to Heron. Any idea what could be causing this?

Answer 1

This is not really an answer. It is too long for comment, so I have to create an answer....

Hard to tell the issue so far, this is the expected output with almost latest code fyi.

For "local", the topology state data is stored in ~/.herondata/repository/state/local//. In your case, you may check if this file is created and contains correct information: ~/.herondata/repository/state/local/schedulers/WindowedWordCountTopology
