[jira] [Created] (HDFS-13433) webhdfs requests can be routed
incorrectly in federated cluster
Arpit Agarwal created HDFS-13433:
------------------------------------
Summary: webhdfs requests can be routed incorrectly in federated cluster
Key: HDFS-13433
URL: https://issues.apache.org/jira/browse/HDFS-13433
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
In the following HA+Federated setup:
# NS1 -> namenodes nn1, nn2
# NS2 -> namenodes nn3, nn4
# fs.defaultFS is {{hdfs://ns1}}.
A webhdfs request issued to nn3 will be routed to nn1. This is because {{setClientNamenodeAddress}} initializes {{NameNode#clientNamenodeAddress}} using fs.defaultFS before the config is overriden.
