> Project: Hadoop HDFS
> Issue Type: Improvement

> Now the value of PacketReceiver#MAX_PACKET_SIZE is fixed and the size is 16M.
> This value should be configurable to facilitate better performance in
> different environments. For example, when the network environment is poor, or
> the machine quality is not good, and the hard disk quality is not good, this
> value should be set below 16M, such as 8M, which will be more conducive to
> the stability of the cluster.
