Subject [jira] Updated: (HADOOP-2916) Refactor src structure, but leave package structure alone
Date Thu, 29 May 2008 19:11:45 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sanjay Radia updated HADOOP-2916:
---------------------------------

    Description: 
This Jira proposes that the src structure be split  as below.
 The package structure remains the same for this Jira. (Package renaming is part of other
JIras  such as HADOOP-2885).

The idea is that the src will be split   BEFORE the package restructuring

The new proposed src structure is

src/test - unchanged

src/java - will no longer exist , its content will be move to one of core, hdfs, or mapred

src/core - this will contain the core classes that hadoop applications need to link against.
  It will contain client side libraries of  all fs file systems:  local, hdfs, kfs, etc


   src/core/org.apache.hadoop.{conf, fs, filechache, io, ipc, log, metrics, net, record, security,
tools, util)
   src/core/org.apache.hadoop.dfs - this will contain only the client side parts of dfs.
                   HADOOP-2885 will rename package dfs  to package  fs.hdfs 

src/hdfs/org.apache.hadoop.dfs - this will contain only the server side of hdfs. 
      HADOOP-2885 will rename package dfs  to package  fs.hdfs later; a compatible dfs.DistributedFileSystem
will be left for compatibility/


src/mapred/org.apache.hadoop.mapred.*

This Jira will not split the jar files.

      HADOOP-2885 will rename package dfs  to package  fs.hdfs later; a compatible dfs.DistributedFileSystem
will be left for compatibility/
   jar name hadoop_hdfs.jar - this jar can be used to launce NNs and DNs etc.

src/mapred/org.apache.hadoop.mapred.*
   Initially one jar:  hadoop_mapred.jar
   Later this may be split into client-side and server-side jars.
