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.
