def fetchBlockSync(host: String, port: Int, execId: String, blockId: String): ManagedBuffer

A special case of fetchBlocks, as it fetches only one block and is blocking.

def fetchBlocks(host: String, port: Int, execId: String, blockIds: Array[String], listener: BlockFetchingListener): Unit

Fetch a sequence of blocks from a remote node asynchronously, available only after init is invoked.
Fetch a sequence of blocks from a remote node asynchronously, available only after init is invoked.
Note that this API takes a sequence so the implementation can batch requests, and does not return a future so the underlying implementation can invoke onBlockFetchSuccess as soon as the data of a block is fetched, rather than waiting for all blocks to be fetched.
