Nan Zhu commented on SPARK-3957:
--------------------------------

After looking at the problem more closely, I think we might just set the 
tellMaster flag to true to get this information (after put, it will report to 
BlockManagerMaster), instead of introducing a fat heartbeat message or open new 
channel

the only thing we need to add is that, we need distinguish RDD and broadcast 
variable in BlockStatus....

how you guys think about it?

> Memory used by broadcast variables are not reflected in the memory usage 
> reported in the WebUI. For example, the executors tab shows memory used in 
> each executor but this number doesn't include memory used by broadcast 
> variables. Similarly the storage tab only shows list of rdds cached and how 
> much memory they use.  
> We should add a separate column / tab for broadcast variables to make it 
> easier to debug.
