--------------------------------
Summary: Allow multiple net interfaces to be used with HA namenode
RPC server
Key: HDFS-5128
URL: https://issues.apache.org/jira/browse/HDFS-5128
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Kihwal Lee
Priority: Critical
With the new RPCv9, NN RPC server can be bound to multiple IP addresses and
serve clients connecting to different addressed using the same SPN. But the
only way to have NN bind to multiple addresses is to set its RPC address to
0.0.0.0. This does not work well with HA especially when name nodes share the
same config.
I propose a new option for NN rpc server to bind to all interfaces, independent
of the rpc address configuration.
