Hi Jens Ok, so you are running it on Hadoop 2 then.
Now if you look at https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/node/internal/InternalSettingsPreparer.java#L114 you'll see that if it does not have a name, it will try to load one randomly from a file (names.txt) and judging by https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/common/Names.java#L45 that file must be empty or non existent. That file names.txt lives in the elasticsearch jar. The explanation that comes to mind is that using Nutch in deployed mode means that this file is not loaded. I have used ES in distributed mode with Hadoop 1.x so it could be that there is a difference in Hadoop 2 (which we do not yet officially support BTW) or a difference with my configuration which would explain why I did not get this issue.
