> This JIRA is to use {{BlockInfo[] blocks}} for both striped and contiguous
> blocks in INodeFile.
> Currently {{FileWithStripedBlocksFeature}} keeps separate list for striped
> blocks, and the methods there duplicate with those in INodeFile, and current
> code need to judge {{isStriped}} then do different things. Also if file is
> striped, the {{blocks}} in INodeFile occupy a reference memory space.
> These are not necessary, and we can use the same {{blocks}} to make code more
> clear.
> I keep {{FileWithStripedBlocksFeature}} as empty for follow use: I will file
> a new JIRA to move {{dataBlockNum}} and {{parityBlockNum}} from
> *BlockInfoStriped* to INodeFile, since ideally they are the same for all
> striped blocks in a file, and store them in block will waste NN memory.
