Kylin Soong commented on TEIID-3124:
------------------------------------

Root Cause
==========
No hostname IP mapping cause InetAddress.getLocalHost() throw java.net.UnknownHostException, this trigger teiid-runtime SocketConfiguration.java as [1] line 79 throw UnknownHostException, but the exception be swallowed, instead with the TeiidRuntimeException


How reproducible:
================

The following steps for reproduce the issue in Rad Hat Linux 6

1. edit the /etc/sysconfig/network, set a hostname, below is the setting in my machine:
~~~
NETWORKING=yes
HOSTNAME=kylin.redhat.com
~~~
Note: the logout is necessary for let hostname take effect

2. start the JDV 
~~~
/standalone.sh
~~~
Note the TeiidRuntimeException throw, this due to SocketConfiguration as [1] line 79 InetAddress.getLocalHost() return UnknownHostException, the swallowed exception like below:
~~~
Caused by: java.net.UnknownHostException: kylin.redhat.com: Name or service not known
	at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
	at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:901)
	at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1293)
	at java.net.InetAddress.getLocalHost(InetAddress.java:1469)
	... 1 more
~~~

3. edit /etc/hosts, add hostname IP mapping as below:
~~~
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 kylin.redhat.com
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 kylin.redhat.com
~~~
Note: the kylin.redhat.com are new appended


Expected results
================

Change the SocketConfiguration resolveHostName() method, InetAddress.getLocalHost()have risk while look up local address via hostname, if no address are mapped the code throw exception, cause service start up failed
