As following error happened, when I running Twitter Heron on local machine using the command: 

heron activate local WordCountTopology.

The error information:

[root@localhost Desktop]# heron activate local WordCountTopology
[2017-12-02 05:23:32 +0000] [INFO]: Using cluster definition in /usr/local/heron/conf/local

It will be great if we can see the verbose logs - can you please do the following?

heron activate local --verbose WordCountTopology

It will print several logs and this will help identify if there is an issue.

  • Based on hidden part of the logs, it looks you launched the topology as 'root' and you are trying to activate the topology by the user 'yitian' - that could be an issue. Try activating the topology as 'root' - which is the original user that launched the topology. – Karthik Dec 06 '17 at 20:44
  • thanks for your suggestion, I have solved the problem. There are some exception when Heron 0.17.1 running on the CentOS 6.4 version. It is normal when heron running on Centos 7. Although this problem can be solved by using following command: $ heron activate local/root/default WordCountTopology, it is suggestion that using CentOS 7 version deploy heron. – Yitian Zhang Dec 13 '17 at 02:44
