> After some debug works´╝îI found that when hfile closing, if the rootChunk is empty,
the only one curInlineChunk will upgrade to root chunk. But if the last block flushing make
curInlineChunk exceed max index block size, the root chunk(upgrade from curInlineChunk) will
be splited into intermediate index blocks, and the index level is set to 2. So when BlockIndexReader
read the root index, it expects the next level index block is leaf index(index level=2), but
the on disk index block is intermediate block, the error happened. 
> After I add some code to check curInlineChunk's size when rootChunk is empty in shouldWriteBlock(boolean
closing), this bug can be fixed.
