Doug Cutting commented on HADOOP-2916:
--------------------------------------
Why make this change independent of HADOOP-2885? In either case, HADOOP-2885
will not be implementable as a patch file, but will require direct svn
operations to rename files. Both issues will break other existing patch files.
So why not combine them?
Perhaps what should be submitted for things like this is a shell script that's
run before any patches are applied. This can do all of the 'svn mkdir' and
'svn mv' commands. Ideally hudson would even run such scripts, but, in the
meantime, it will at least let others preview what's intended. So the
procedure would be:
{noformat}
sh svn-commands.sh
patch -p 0 < patch.txt
{noformat}
> Refactor src structure, but leave package structure along

> Key: HADOOP-2916
> URL: https://issues.apache.org/jira/browse/HADOOP-2916
> Project: Hadoop Core
> Issue Type: Sub-task
> Components: dfs
> Reporter: Sanjay Radia
> Assignee: Raghu Angadi
> Fix For: 0.17.0
>
>
> 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 exit , 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
> jar name hadoop_core.jar
> 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/
> 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.
