Description

the

{NN_HOST} defined in appConfig.json,the value will be from fs.defaultFs
AgentProviderService#getStandardTokenMap
String nnuri = appConf.get("site.fs.defaultFS");
tokens.put("$ {NN_URI}
", nnuri);
tokens.put("${NN_HOST}

", URI.create(nnuri).getHost());
eg:
hdfs://test1:8020/ will return hostname test1

but when enable HA,
fs.defaultFS <= hdfs://nn/
the nn is not a hostname
