Subject [jira] [Commented] (MAPREDUCE-2842) Maven build issues in MR2
Date Tue, 16 Aug 2011 23:51:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086047#comment-13086047
] 

Alejandro Abdelnur commented on MAPREDUCE-2842:
-----------------------------------------------

The proposal is that artifact/module names would be:

{code}
trunk/:
  mapreduce -> hadoop-mapreduce

trunk/hadoop-mapreduce/:
  mr-client -> hadoop-mr-client
  yarn -> hadoop-yarn

trunk/hadoop-mapreduce/hadoop-yarn:
  yarn-api -> hadoop-yarn-api
  yarn-common -> hadoop-yarn-common
  yarn-server -> hadoop-yarn-server

trunk/mapreduce/hadoop-yarn/hadoop-yarn-server:
  yarn-server-common -> hadoop-yarn-server-common
  yarn-server-nodemanager -> hadoop-yarn-server-nodemanager
  yarn-server-resourcemanager -> hadoop-yarn-server-resourcemanager
  yarn-server-tests -> hadoop-yarn-server-tests
{code}

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: build, mrv2
>    Affects Versions: 0.23.0
>            Reporter: Alejandro Abdelnur
>              Labels: maven
>             Fix For: 0.23.0
>
>
> * mapreduce has not been rebased on top of trunk
> * mapreduce dir/module should be named hadoop-mapreduce (following convention of common,
hdfs)
> * there is lot of stuff under mapreduce that seems stale (bin/, conf, ivy/, lib/ src/)
> * yarn* dirs/modules should be named hadoop-yarn* (following convention of other Hadoop
artifacts)
> * yarn/bin/ scripts should be under yarn/src/main/bin
> * yarn/conf/ scripts should be under yarn/src/main/conf
> * JAR POM files do not use hadoop-project POM as parent
> * some POM files have version parameterized and this will break things for people consuming
JARs from Maven repos
> * mapreduce is not using assembly from hadoop-assemblies (the changes introduced by HDFS-2096
make the assembly/packaging reusable across different components)
