Varun Thacker commented on SOLR-11278:
--------------------------------------
Looks like it was happy for 1 day but today I see a failure :
https://jenkins.thetaphi.de/job/Lucene-Solr-7.x-Linux/517/
I won't get time to look at this for another till tuesday atleast . Let's not
hold up 7.0.1 for this?
People who hit this race condition in 7.0 can fix it by restarting the target
cluster as the bootstrap will fail. Not the best experience but they are
starting a new cluster so hopefully not a big deal.
> Fix race in cdcr bootstrap process
