[jira] [Updated] (NIFI-5434) ExecuteScript/Jython imports fail
randomly
[ https://issues.apache.org/jira/browse/NIFI-5434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wietze B updated NIFI-5434:
---------------------------
Description:
I have a number of ExecuteScript processors running Jython that import libraries such as {{threading}}, {{urllib3}}, {{requests}}, etc.
When I boot up my machine or initially start the NiFi service, the ExecuteScript processors relying on external libraries usually to don't work straight away, throwing {{AttributeError}} s or {{ImportError}} s on libraries that definitely exist and are accessible. Restarting the machine or the NiFi service again usually fixes the problem, but it is unclear to me why the imports sometime fail, and sometimes work.
See attached two screenshots and an extract from the logs.
