Till Rohrmann updated FLINK-2156:
---------------------------------
    Description: 
The Scala only modules {{flink-scala-shell}} and {{flink-ml}} use Maven's 
scalatest plugin to run their tests. The scalatest plugin has no 
{{forkNumber}}, though. Therefore, the logging fails to create the logging file 
as specified in the {{log4j-travis.properties}} file.

We can fix this issue by giving these two modules different 
{{log4j.properties}} files which don't require a {{forkNumber}}. Or we fix the 
{{forkNumber}} to 1.
