Hm, this is not a public API, but you should theoretically be able to use TestBlockId if you like. Internally, we just use the BlockId's natural hashing and equality to do lookups and puts, so it should work fine. However, since it is in no way public API, it may change even in maintenance releases.

 When spark is 0.7.3, I use SparkEnv.get.blockManager.getLocal("model") and SparkEnv.get.blockManager.put("model", buf, StorageLevel.MEMORY_ONLY, false) to cached model object

When I porting to spark 1.0.1, I found  SparkEnv.get.blockManager.getLocal & ‍SparkEnv.get.blockManager.put's APIs changed to use BlockId instead of String. 
 

And BlockId has 5 concrete class, which one should I use? None of them have a string input parameter.‍‍
