[jira] [Created] (MAPREDUCE-6117) Hadoop ignores
yarn.resourcemanager.hostname for RPC listeners
Waldyn Benbenek created MAPREDUCE-6117:
------------------------------------------
Summary: Hadoop ignores yarn.resourcemanager.hostname for RPC listeners
Key: MAPREDUCE-6117
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6117
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client, task
Affects Versions: 2.5.1, 2.4.1, 2.2.1
Environment: Any mapreduce example with standard cluster. In our case each node has four networks. It is important that all internode communication be done on a specific network.
Reporter: Waldyn Benbenek
The RPC listeners for an application are using the hostname of the node as the binding address of the listener, They ignore yarn.resourcemanager.hostname for this. In our setup we want all communication between nodes to be done via the network addresses we specify in yarn.resourcemanager.hostname on each node.
TaskAttemptListenerImpl.java and MRClientService.java are two places I have found where the default address is used rather that RM_host. The resource Manager hostname should be used for all communication between nodes including the RPC listeners.
