Harsh J commented on HDFS-7397:
-------------------------------

I don't think there's a great need to change the property name, but we could 
clarify what the description says about it (hdfs-default.xml). Being an 
advanced property, the description of it will help ascertain what the value 
needs to be for users wanting to change it.

> The conf key "dfs.client.read.shortcircuit.streams.cache.size" is misleading

> For dfs.client.read.shortcircuit.streams.cache.size, is it in MB or KB?  
> Interestingly, it is neither in MB nor KB.  It is the number of shortcircuit 
> streams.
