    Description

      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.
