[jira] [Commented] (AIRFLOW-217) Getting AttributeError: 'DAG' object has no attribute 'task_dict' while using Celery Executor

    [ https://issues.apache.org/jira/browse/AIRFLOW-217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15321180#comment-15321180 ] 

Navjot commented on AIRFLOW-217:
--------------------------------

We already resolved this problem. We were running different versions of Airflow on master and worker. Now we are using Ubuntu instances with same versions of Airflow on master and workers.  I don't know if that was the problem but its working now, worker is picking up jobs.

> We are trying to implement airflow to run some data intensive processess
> I am trying to run a job on worker using Celery executor. I have configured all the settings but still it is not running the job. I am getting some weird error, I couldn't find information about it on forums.
