        Hi Tsz Wo Nicholas Sze

        can we change like dfs.client.read.shortcircuit.streams.cache.num/count..?

        I feel, following also we can check, Please correct me If I am wrong.

        public static final String  DFS_CLIENT_SOCKET_CACHE_CAPACITY_KEY = "dfs.client.socketcache.capacity";
        public static final int     DFS_CLIENT_SOCKET_CACHE_CAPACITY_DEFAULT = 16;

        How about dfs.client.read.shortcircuit.streams.count?

        > I feel, following also we can check, Please correct me If I am wrong.

        Sorry, I don't understand what do you mean. Could you explain?

        What I mean is can we change "dfs.client.socketcache.capacity" also like dfs.client.socketcache.num/count..?

        How about dfs.client.read.shortcircuit.streams.count?

        I am ok with this..( But here we are missing "cache", since connections will be cached)..

        I see. How about dfs.client.read.shortcircuit.cache.block-count-max? The word "block" seems better than "stream".

        > Why not just add some text to the description in hdfs-default.xml?

        Do you agree that "dfs.client.read.shortcircuit.streams.cache.size" is misleading?

        dfs.client.read.shortcircuit.cache.block-count-max?

        We're not caching blocks, we're caching file descriptors.

        Do you agree that "dfs.client.read.shortcircuit.streams.cache.size" is misleading?

        To be honest, I think the current name is fine. This is a cache of file descriptors. You can't cache half a file descriptor, hence questions like "is it in kb or mb" have no meaning. That is why I suggested updating the docs. I do not feel strongly about it, though.

        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.

        I'm not sure that this is clearer. It's actually shorter and snips out the first sentence which describes what the cache is.

        If anything would make this clearer, it might be changing "This parameter controls the size of that cache" to "This parameter controls the maximum number of file descriptors in the cache."
