unable to canonicalize address xxx:2181 because it's not resolvable

[panda0120]

I create a graph by ConfiguredGraphFactory.createConfiguration(new MapConfiguration(map)); But the storage.hostname is wrong in the map, then the janusgraph log error like "unable to canonicalize address xxx:2181 because it's not resolvable".Someone knows how to fix it?I try to update the configuration or drop it,but it's not working

groovy code :

map = new HashMap<String, Object>();
map.put("storage.backend", "hbase");
map.put("storage.hostname", "node1");
map.put("index.search.backend", "elasticsearch");
map.put("index.search.hostname", "172.17.0.130:9200);
map.put("storage.batch-loading", true);
map.put("storage.buffer-size", "102400");
map.put("graph.set-vertex-id", true);
map.put("graph.allow-custom-vid-types", true);
map.put("schema.default", "none");
map.put("graph.graphname", graphName);
ConfiguredGraphFactory.createConfiguration(new MapConfiguration(map));

I find the reason.It's because I execute a script to create and open the graph,when the hostname is wrong, the script keep hunging on the open api in the janusgraph server, Even my java client is closed.
Then when I execute ConfiguredGraphFactory.updateConfiguration,the server will keep hunging until the timeout error is throwed;
I want to know how to restore my janusgraph server.
