Subject [jira] [Commented] (CONNECTORS-1581) [Set priority thread] Error tossed: null during startup
Date Mon, 11 Feb 2019 17:15:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16765173#comment-16765173
] 

Markus Schuch commented on CONNECTORS-1581:
-------------------------------------------

{code}
select jobid, count(jobid), jobs.description from jobqueue left outer join jobs on jobs.id
= jobqueue.jobid group by jobid;
{code}
actually returns 1 row with documents not having a existing job.
These items belong to a job that we deleted some time ago. For some reason the cleanup did
not work properly.

[~kwright@metacarta.com] Is it safe to delete those rows from the jobqeue table?
