(Doc ID 2032401.1)

Last updated on MAY 01, 2017

Applies to:

Big Data Appliance Integrated Software - Version 4.2.0 and later
Linux x86-64

Symptoms

On BDA V4.2/CDH 5.4 the ResourceManager (RM) is observed not to be listening on all interfaces even though the Cloudera Manager (CM) configuration parameter "Bind ResourceManager to Wildcard Address" is enabled.  The RM is found to be listening only over the InfiniBand addresses. Not listening on all interfaces prevents access from clients that connect externally and run jobs, such as spark-shell, etc. as they do not go over the InfiniBand network.

Symptoms include:

1. In Cloudera Manager "Bind ResourceManager to Wildcard Address" is set. In CM navigate:

Home > yarn > Configuration > Search for: "Bind ResourceManager to Wildcard Address"

Observe that it is enabled allowing the RM to listen on all of its ports:




2. On the Active RM node (typically Node 3 or Node 4 but verify in  CM yarn > Instances) the RM ports listen on the IB network:

See the RM ports 8030, 8031, 8032, 8033 listening on the IB network:
