> Ideally, for striped block, an internal block is only on one datanode, so {{DFSStripedInputStream#seekToNewSource}} should return *false*, we should overwrite {{DFSInputStream#seekToNewSource}} for striped file.
> This patch also remove the hardcode for {{groupSize}}
> {code}
> private final short groupSize = HdfsConstants.NUM_DATA_BLOCKS;
> {code}
