-----------------------------------
Summary: DocumentNodeStore: Error calculating the machine id
Key: OAK-2112
URL: https://issues.apache.org/jira/browse/OAK-2112
Project: Jackrabbit Oak
Issue Type: Improvement
Components: mongomk
Reporter: Thomas Mueller
Assignee: Thomas Mueller
Priority: Minor
Fix For: 1.1
In some cases, the machine id (which is used to identify the cluster id) can
not be calculated. The exception is a bit strange:
{noformat}
java.net.SocketException: No such device
at java.net.NetworkInterface.getMacAddr0(Native Method)
at
java.net.NetworkInterface.getHardwareAddress(NetworkInterface.java:388)
at
org.apache.jackrabbit.oak.plugins.document.ClusterNodeInfo.getMachineId(ClusterNodeInfo.java:454)
{noformat}
The exception should be logged as a warning, not an error. Also, the next
network interface could be tried out.
