Major Description
SamzaContainer initializes ExponentialSleepStrategy with randInt for initialDelay, when reading the JobModel.
randInt is inclusive of 0. initialDelay cannot be 0 in a backoff approach. The assert check in ExponentialSleepStrategy ends up failing the container occasionally. This should be fixed to not include 0 for initialDelay.
As a side note: This also causes occasional build failure because the unit test for reading JobModel fails. Hence, it is important to fix this.
