fulin wang commented on HBASE-5874:
-----------------------------------
I have tested, It pass.
There is some reason for add 'fs.default.name' attribute.
1) It make hbck tool and Merge tool easy to use.
2) We should supported old version, you can reference the MasterFileSystem
class.
I suggested to add the attribute.
> The HBase do not configure the 'fs.default.name' attribute, the hbck tool and
> Merge tool throw IllegalArgumentException.
