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; org.apache.solr.cloud.RecoveryStrategy;
Recovery failed - trying again... (16) core=cams_shard1_replica4
ERROR - 2014-11-12 15:17:34.230; org.apache.solr.common.SolrException;
Error while trying to recover.

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