> Currently HdfsServerConstants reads the configuration and to set the value of
> IO_FILE_BUFFER_SIZE and SMALL_BUFFER_SIZE, thus they are configurable instead
> of being constants.
> This jira proposes to move these two variables to the users in the
> upper-level so that HdfsServerConstants only stores constant values.
