Aaron T. Myers created HDFS-4448: ------------------------------------ Summary: HA NN does not start with wildcard address configured for other NN when security is enabled Key: HDFS-4448 URL: https://issues.apache.org/jira/browse/HDFS-4448 Project: Hadoop HDFS Issue Type: Bug Components: ha, namenode, security Affects Versions: 2.0.3-alpha Reporter: Aaron T. Myers Assignee: Aaron T. Myers
Currently if one tries to configure HA NNs use the wildcard HTTP address when security is enabled, the NN will fail to start with an error like the following: {code} java.lang.IllegalArgumentException: java.io.IOException: Cannot use a wildcard address with security. Must explicitly set bind address for Kerberos {code} This is the case even if one configures an actual address for the other NN's HTTP address. There's no good reason for this, since we now check for the local address being set to 0.0.0.0 and determine the canonical hostname for Kerberos purposes using {{InetAddress.getLocalHost().getCanonicalHostName()}}, so we should remove the restriction. -- This message is automatically generated by JIRA.
