-----------------------------------
Summary: KerberosAuthenticator should use the configured principal
Key: HADOOP-8554
URL: https://issues.apache.org/jira/browse/HADOOP-8554
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 1.0.0
Reporter: Eli Collins
In KerberosAuthenticator we construct the principal as follows:
{code}
String servicePrincipal = "HTTP/" + KerberosAuthenticator.this.url.getHost();
{code}
Seems like we should use the configured
hadoop.http.authentication.kerberos.principal instead right?
I hit this issue as a distcp using webhdfs://localhost fails because
HTTP/localhost is not in the kerb DB but using webhdfs://eli-thinkpad works
because HTTP/eli-thinkpad is (and is my configured principal). distcp using
Hftp://localhost with the same config works so it looks like this check is
webhdfs specific for some reason (webhdfs is using spnego and hftp is not?).
