Hi, A few points:
- The property "fs.default.name" has been deprecated in favor of the newer name "fs.defaultFS". - When using nameservice IDs, you shouldn't rely on the RPC address. That is, your fs.defaultFS should instead simply be "hdfs://ns1", and the config will load the right RPC that is bound to that NS automatically from the hdfs-site.xml.
