I happened to have Jupyter running in my machine in port 8888.
When running the tests, I got:
{code}
Caused by: java.net.BindException: Problem binding to [localhost:8888]
java.net.BindException: Address already in use: bind; For more details see:
http://wiki.apache.org/hadoop/BindException
{code}
A quick solution would be to do something like:
{code}
// Start routers with only an RPC service
Configuration routerConf = new RouterConfigBuilder()
.metrics()
.rpc()
.build();
routerConf.set("dfs.federation.router.rpc-address", "0.0.0.0:0");
conf.addResource(routerConf);
Router router = new Router();
router.init(conf);
router.start();
{code}
But maybe we want to set this a little more general.
The MiniRouterDFSCluster already does:
{cluster}
public Configuration generateRouterConfiguration(String nsId, String nnId) {
Configuration conf = new HdfsConfiguration(false);
conf.addResource(generateNamenodeConfiguration(nsId));
conf.setInt(DFS_ROUTER_HANDLER_COUNT_KEY, 10);
conf.set(DFS_ROUTER_RPC_ADDRESS_KEY, "127.0.0.1:0");
conf.set(DFS_ROUTER_RPC_BIND_HOST_KEY, "0.0.0.0");
...
{cluster}
