Hi there!
As we got bitten by https://issues.apache.org/jira/browse/SOLR-6530 on
a regular basis, we started upgrading our 7 mode cloud from 4.10.1 to
4.10.2.
The first node upgrade worked like a charm.
After upgrading the second node, two cores no longer come up and we
get the following error:
ERROR - 2014-11-12 15:17:34.226;

again... (16) core=cams_shard1_replica4

Any hint on how to solve this? Google didn't reveal anything useful...
Kind regards

The leader for both collections (solr-bc1-blade2) is still on 4.10.1.
As no special instructions were given in the release notes and it's a
minor upgrade, we thought there should be no BC issues and planned to
upgrade one node after the other.
Did that provide more insight?
