Subject [GitHub] keith-turner opened a new issue #973: MiniFluo fails to start when running from mvn exec

keith-turner opened a new issue #973: MiniFluo fails to start when running from mvn exec
URL: https://github.com/apache/fluo/issues/973
 
 
   When trying to use maven exec to start a 1.2.0-SNAPSHOT instance of mini fluo it fails
with the following exeception.  I think what is happening is that the fluo jars are found
on the classpath and then it tries to copy those to hdfs.  However there is no HDFS.  
   
   I am thinking a possible fix for this is to make the the new `fluo.dfs.root`  property
not have a default of localhost.   Also make the copytojars code that uses the property do
nothing if the property is not set.
   
   Could possibly throw an exception if `fluo.accumulo.jars` is set and `fluo.dfs.root` is
not.  However when both are not set, then do nothing.
