> DistCp won't reassemble chunks when blocks per chunk > 0

> I was investigating why hadoop-distcp-2.9.2 won't reassemble chunks of the 
> same file when blocks per chunk has been set > 0.
> In the CopyCommitter::commitJob, this logic can prevent chunks from 
> reassembling if blocks per chunk is equal to 0:
> {code:java}
> if (blocksPerChunk > 0) {
>   concatFileChunks(conf);
> }
> {code}
> Then in CopyCommitter's ctor, blocksPerChunk is initialised from the config:
> {code:java}
> blocksPerChunk = context.getConfiguration().getInt(
> DistCpOptionSwitch.BLOCKS_PER_CHUNK.getConfigLabel(), 0);
> {code}
>  
> But here the config key DistCpOptionSwitch.BLOCKS_PER_CHUNK.getConfigLabel() 
> will always returns empty string because it is constructed without config 
> label:
> {code:java}
> BLOCKS_PER_CHUNK("",
> new Option("blocksperchunk", true, "If set to a positive value, files"
> + "with more blocks than this value will be split into chunks of "
> + "<blocksperchunk> blocks to be transferred in parallel, and "
> + "reassembled on the destination. By default, <blocksperchunk> is "
> + "0 and the files will be transmitted in their entirety without "
> + "splitting. This switch is only applicable when the source file "
> + "system implements getBlockLocations method and the target file "
> + "system implements concat method"))
> {code}
> As a result it will fall back to the default value 0 for blocksPerChunk, and 
> prevent the chunks from reassembling.
