Azkaban: Task stays preparing












0















I successfully installed Azkaban. The web page can be visited and using jps I can see the two processes:



AzkabanWebServer
AzkabanExecutorServer


I create a project and successfully upload a workflow.zip file. However, when I select of job and click 'Run job', the job remains 'preparing'. The task is in 'executing list' but log page is empty.



I checked all *.out and *.log files of both web_server and executor_server, but there is no exception info at all.



How to address this issue? Any help is appreciated.



ps: log and out files:1. executor.log
