> Reversed Scan usage on Shell:
> hbase> scan 't1', {REVERSED => true}
> Other parameter could also be added with 'REVERSED', like LIMIT,COLUMNS.
> Here is how boolean argument is accepted:

> cache_blocks = args["CACHE_BLOCKS"] || true
> {code}
> Flag for reverse scan should be supported in similar manner
