I'm running flink-1.1.4-bin-hadoop27-scala_2.11 and I'm running into an issue where after some period of time (measured in 1 - 3 hours) the JobManager gets an NPE and shuts itself down. The failure is at JobManager$$updateAccumulators$1.apply(JobManager.scala:1790). I'm using a custom accumulator[1], but can't tell from the JobManager code whether the issue is in my Accumulator, or is a bug in the JobManager.
