Shalin Shekhar Mangar commented on SOLR-6206:
---------------------------------------------
Sorry, the changes in this patch were not required because we were already
deleting the temporary collection at the start of the migrateKey method. We
only need to do the following:
{code}
try {
deleteCollection(new ZkNodeProps(props), results);
+ clusterState = zkStateReader.getClusterState();
} catch (Exception e) {
log.warn("Unable to clean up existing temporary collection: " +
tempSourceCollectionName, e);
}
{code}
We just need to refresh the cluster state object after deleting the collection
for re-tries to work. I'll commit this change.
