--------------------------------------
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]).
