tay commented on SOLR-4570:
---------------------------
solr 6.0 version，explicit shard id in core.properties. but where restart,solr
use the shard id from clusterstate .not come from croe.preperties.
find ZkController#preRegister. allways invoke
doGetShardIdAndNodeNameProcess method :
if (cd.getCloudDescriptor().getShardId() == null &&
needsToBeAssignedShardId(cd, zkStateReader.getClusterState(), coreNodeName)) {
doGetShardIdAndNodeNameProcess(cd);
} else {
// still wait till we see us in local state
doGetShardIdAndNodeNameProcess(cd);
}
so explicit shard id is not used
> Even if an explicit shard id is used, ZkController#preRegister should still
> wait to see the shard id in it's current ClusterState.
