Chesnay Schepler commented on FLINK-989:
----------------------------------------

would this be sufficient?

{code:java}
throw new SchedulingException("Not enough slots to schedule job " + executionGraph.getJobID()
+ " Req.: " + requiredSlots + " Avail.: " + availableSlots + ". Either reduce the DOP of your program, "
+ "wait for other programs to finish or configure the number of slots in conf/flink-conf.yaml .");
{code}
