--------------------------------
Summary: Move HdfsServerConstants#IO_FILE_BUFFER_SIZE and
SMALL_BUFFER_SIZE to the users
Key: HDFS-8314
URL: https://issues.apache.org/jira/browse/HDFS-8314
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Haohui Mai
Assignee: Haohui Mai
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.
