> With HFile v2 implementation in HBase 0.94 & 0.96, the region server will use HFileSystem as its {color:blue}fs{color}. When it performs bulk load in Store.bulkLoadHFile(), it checks if its {color:blue}fs{color} is the same as {color:blue}srcFs{color}, which however will be DistributedFileSystem. Consequently, it will always perform an extra copy of source files.
