When following mr-279/INSTALL to compile source, it throws the
following error in the second step to compile HDFS-1052. How to solve
this problem?

Why are you compiling branch HDFS-1052?, it was a temporary branch for
merging federated NN changes into trunk. All the changes in that
branch have since been merged into trunk and MR-279. These stale
branches should be deleted, IMO.

MR-279 only supports the common and hdfs in the same branch, though
we're moving to trunk soon.

I was not aware that the source downloaded (a few months ago) is
obsoleted. So now I switch by doing svn update, which solves the code
obsolete issue.

Then I follow the instruction at mapreduce/INSTALL [1], which points
to install depdencies for yarn first at README[2]. During searching
mailing list, it seems avro plugin is not necessary to install
manually. So I only install protobuf 2.4.1 (configure/ make/ make
install works ok.) But after that, a mvn install under mapreduce
produces error

 Failed to execute goal on project yarn-api: Could not resolve
dependencies for project org.apache.hadoop:yarn-api:jar:1.0-SNAPSHOT:
Failure to find org.apache.hadoop:hadoop-hdfs:jar:0.22.0-SNAPSHOT in
https://repository.jboss.org/nexus/content/groups/public-jboss/ was
cached in the local repository, resolution will not be reattempted
until the update interval of jboss-public-repository-group has elapsed
or updates are forced -> [Help 1]

That looks like missing the hdfs jar artifact. So cd to mr-279/hdfs
and execute `ant clean package` generates error message as shown in
compile-hdfs-classes section.

What is the right order/ procedure to successfully compile mr-279? Or
will have a new update for the instruction?

Thanks for help.

Did you build common and hdfs before doing mvn install in mapreduce?  You
have to build them in order as stated in INSTALL doc - common, hdfs, then
mapreduce.

Thanks. Recompiling common and hdfs by commands

1st. compile commons
    ant veryclean mvn-install (hadoop-common-0.22.0-SNAPSHOT.jar is
installed to m2 repository)

2nd. compile hdfs
    ant veryclean mvn-install -Dresolvers=internal  (It installs
hadoop-hdfs-0.22.0-SNAPSHOT.jar to repository)

seem to solve the problem below

compile-hdfs-classes:
   [javac] mr-279/hdfs/build.xml:339: warning: 'includeantruntime' was
not set, defaulting to build.sysclasspath=last; set to false for

   [javac] mr-279/hdfs/src/java/org/apache/hadoop/hdfs/server/datanode/DataNode.java:119:

   ...

Now the issue seems to be how to build avro-maven-plugin-1.4.0?

I execute the command

    export MAVEN_OPTS=-Xmx512m
    mvn clean install assembly:assembly

would produce error

[ERROR] Failed to execute goal
org.codehaus.mojo:exec-maven-plugin:1.2:exec (generate-sources) on
project yarn-api: Command execution failed. Process exited with an
error: 127(Exit value: 127) -> [Help 1]

But the avro maven plugin obtained from
https://github.com/phunt/avro-maven-plugin.git only provide 1.0. Would
modify version (pointing it to 1.4.0) in pom work? Or what is the next
step for building yarn-api?

Thanks for help.

The fact you're mentioning avro plugin indicating that I think you're
playing with obsolete patches. The current code uses avro-maven-plugin
1.5.1 which is available via maven central.

Please follow the current instruction here:
http://svn.apache.org/repos/asf/hadoop/common/branches/MR-279/mapreduce/INSTALL

I have updated the MAPREDUCE-279 jira's description to point to the
above couple of days ago.

I just find out avro maven plugin at

http://archive.apache.org/dist/avro/avro-1.5.1/java/avro-maven-plugin-1.5.1.jar

and pom from another place.

Previously my problems are

1st, don not know where the location of avro-maven-plugin
2nd, unable to successfully compile/ install mr-279/hdfs

Now these are solved by downloading avro maven plugin from apache
repository and execute commands pointed out in instruction file.

Thank you for help.
