Subject [jira] [Created] (HADOOP-13032) Refactor FileSystem$Statistics as a separate source file
Date Sat, 16 Apr 2016 02:59:25 GMT
Mingliang Liu created HADOOP-13032:
--------------------------------------

             Summary: Refactor FileSystem$Statistics as a separate source file
                 Key: HADOOP-13032
                 URL: https://issues.apache.org/jira/browse/HADOOP-13032
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
            Reporter: Mingliang Liu
            Assignee: Mingliang Liu
            Priority: Minor


This jira is to track the effort of moving the {{Statistics}} class out of {{FileSystem}}
for:
# shorter source code ({{FileSystem.java}} is gonna have 3780 LoC after [HDFS-10175])
# simpler class structure (the {{Statistics}} is not very straightforward as it's optimized
for performance in [HDFS-5276] and evloving rapidly recently, see [HDFS-9579], [HDFS-10175]
and [MAPREDUCE-6660]).
