Subject [jira] Commented: (HADOOP-2916) Refactor src structure, but leave package structure alone
Date Mon, 19 May 2008 19:23:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598052#action_12598052

Jim Kellerman commented on HADOOP-2916:

-1 on including this in 0.17. It is too radical of a change for a 'patch' release.
+1 on including this in 0.18. Hiding implementation is a good idea.

> 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.
