> Balancer has introduced 2 volatile int as part of HDFS-13783 namely:
> exceptionsSinceLastBalance and failedTimesSinceLastSuccessfulBalance.
> However, we are performing non-atomic operations on it. Since non-atomic
> operations done here mostly depend on their previous values, we should use
> AtomicInteger for both.
