Subject [jira] [Created] (HADOOP-12656) MiniKdc throws "address in use" BindException
Date Thu, 17 Dec 2015 21:13:46 GMT
Wei-Chiu Chuang created HADOOP-12656:

             Summary: MiniKdc throws "address in use" BindException
                 Key: HADOOP-12656
                 URL: https://issues.apache.org/jira/browse/HADOOP-12656
             Project: Hadoop Common
          Issue Type: Bug
         Environment: Jenkins
            Reporter: Wei-Chiu Chuang

Another address in use error.

I saw the test TestKerberosAuthenticationHandler.testNameRules failed due to porting binding

Looking at MiniKdc implementation, if port is 0, the constructor use ServerSocket to find
an unused port, assign the port number to the member variable {{port}} and close the ServerSocket
object; later, in {{initKDCServer()}}, instantiate a TcpTransport object and bind at that

It appears that the port may be used in between, and then throw the exception.
