>
> Currently {{DFSStripedOutputStream#getCurrentBlockGroupBytes}} simply uses
> {{getBytesCurBlock}} of each streamer to calculate the block group size. This
> is wrong when the last stripe is at the block group boundary, since the
> {{bytesCurBlock}} is set to 0 if an internal block is finished.
> For example, when the real block size is {{blockGroupSize - cellSize *
> (numDataBlocks - 1)}}, i.e., the first internal block is full while the
> others are not, the {{getCurrentBlockGroupBytes}} returns wrong result and
> cause the write to fail.
