> The private variable _blockInfo_ in mllib.linalg.distribtued.BlockMatrix is never unpersisted since a BlockMatrix instance is created.
> {code:scala}
>  private lazy val blockInfo = blocks.mapValues(block => (block.numRows, block.numCols)).cache()
> {code}
> I think we should add an API to unpersist this variable.
