CSV Issue imports encounter "Fatal error during import" w/ validator

[JC]

We need to import ~500-2000 issues daily from a legacy ticketing system. Many will be duplicates. We created a validator to locate the duplicates (based off their unique summary) and prevent their creation. The import is performed by end-users on our team, using the issue -> 'import from csv' link

We see a "Fatal error during import" everytime we use the validator

It doesn't matter if its a subtask, or a new issue its always resulted in the issue.

The validator looks like this,

the validator is a "Validation based on JQL query"
JQL Query:

project = "Project Name" AND summary ~ "%{00000}"

Condition: number of issues returned by the JQL query satisfies a boolean expression, with "Ephemeral number 1" (code

{00058}) storing the number of returned issues
Boolean expression:

{00058} = 0

Anybody have any ideas on how we can use this to prevent duplicates without it error out? Ive tried this as an administrator and it throws the same errors as well. We have attempted to import with a clean CSV file thats two lines long to ensure its not related to bad CSV data - and we always face the same issue. 

Thanks!

To be honest I was in a real hurry when I was installing this upgrade and don't remember exactly what fixed it. However, I can give you a few things to check.

Make sure the docbase is set to the right war file in Tomcat's server.xml file and that it's actually loading it. I think my problem was I had an older expanded version of Jira in the webapps folder. I'm not a Tomcat expert but it seemed to me that Tomcat was using this expanded version and ignoring the new WAR file. I deleted the expanded Jira code in the webapps folder and that forced Tomcat to deploy the new WAR file.

Also, make sure jira.home is set to the current home directory. When upgrading I'll create a new home directory just in case I need to backout to the old version.

Again, sorry I can pin down the root cause of the problem.

I'm getting the same issue, with Jira 6.2.5 WAR. Followed the link but I don't have the argument (and also using Java 6).

Any suggestions?

Stupid user error.

This can be closed.

Hi, this stack trace refers to this kb: https://confluence.atlassian.com/display/JIRAKB/Upgrade+failed+due+to+UnsupportedOperationException

You may want to check whether this is the case.

Cheers
