    Description

      In DataInputByteBuffer$Buffer class, the fields bidx and buffers, etc are unsynchronized when used in read() and reset() function. In certain circumstances, e.g., the reset() is invoked in a loop, the unsynchronized bidx and buffers can trigger a concurrency bug.
      This bug also shows in Hadoop-15429.
