Crash after upgrading to es 8.0.0

Elastic Stack Elasticsearch
1

I was about to add a github issue but as I'm not sure what counts as a confirmed bug I report my issue here:

I was running es & kibana 7.17.0 and used kibana migration assistant to re-index my main index called "messages". Assistant was then all green. After that I upgraded to es 8.0.0 and got the following crash:

java.lang.IllegalStateException: Failed to parse mappings for index [[reindexed-v7-messages1-2.4.0/bq-_Zh3KS0-Q_ORWnVekDA]]
Likely root cause: java.lang.IllegalArgumentException: Unknown pattern letter: t

Here are the logs the server manages to print before crashing:

Has anyone else encountered this? Let me know how to provide more info if that's needed. I lost few days of data because of this. Not a big deal but a solution that can repair the index would be nice.

2

In case it matters, I saw this error while upgrading [Upgrade] migration system indices fails for tasks: mapper_parsing_exception · Issue #83779 · elastic/elasticsearch · GitHub After seeing it, I just deleted the task index and proceeded.

3

I couldn't simply downgrade to es7 as it says that the db files have been touched by es8. From the backups I got working es7 setup. Now I can see the following warning

"Camel case format name dateOptionalTime is deprecated and will be removed in a future version. Use snake case name date_optional_time instead."

This probably caused it? And my mistake was not to check the logs, just rely on upgrade assistant?

4

That does seem like the explanation, but I think Elasticsearch should at least not leave you in a state where you can't start it up but nor can you downgrade either. Could you share the complete log output please?

Here is a log when I try to downgrade:
