Description

Currently, updatedBlockStatuses of TaskMetrics does not update correctly when removing blocks in BlockManager.removeBlock and the method invoke removeBlock. See:
branch-1.6:https://github.com/apache/spark/blob/branch-1.6/core/src/main/scala/org/apache/spark/storage/BlockManager.scala#L1108
branch-1.5:https://github.com/apache/spark/blob/branch-1.5/core/src/main/scala/org/apache/spark/storage/BlockManager.scala#L1101
We should make sure updatedBlockStatuses update correctly when:

• Block removed from BlockManager
• Block dropped from memory to disk
• Block added to BlockManager
