Current status

Targeted release: Fedora 20
Last updated: 8 July 2013
Tracker bug: RHBZ #998521

Detailed Description

Apache Hadoop is a widely used, increasingly complete big data platform, with a strong open source community and growing ecosystem. The goal is to package and integrate the core of the Hadoop ecosystem for Fedora, allowing for immediate use and creating a base for the rest of the ecosystem.

Benefit to Fedora

The Apache Hadoop software will be packaged and integrated with Fedora. The core of the Hadoop ecosystem will be available with Fedora and provide a base for additional packages.

Scope

Proposal owners:
- Note: target is Apache Hadoop 2.0.5-alpha
- Package all dependencies needed for Apache Hadoop 2.x
- Package the Apache Hadoop 2.x software

How To Test

Install the hadoop rpms with:
- yum install hadoop-common hadoop-hdfs hadoop-libhdfs hadoop-mapreduce hadoop-mapreduce-examples hadoop-yarn
Start the cluster by issuing:
- systemctl start hadoop-namenode hadoop-datanode hadoop-nodemanager hadoop-resourcemanager
Initialize the HDFS directories:
- hdfs-create-dirs
Create a directory for the user running the tests:
1. runuser hdfs -s /bin/bash /bin/bash -c "hadoop fs -mkdir /user/<name>"
2. runuser hdfs -s /bin/bash /bin/bash -c "hadoop fs -chown <name> /user/<name>"
The user from the previous step can run jobs like the following mapreduce examples:
- hadoop jar /usr/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.5-alpha.jar pi 10 1000000
- hadoop jar /usr/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.5-alpha.jar randomwriter out
- These three have an order they need to be run in:
  1. hadoop jar /usr/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.5-alpha.jar teragen 100 gendata
  2. hadoop jar /usr/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.5-alpha.jar terasort gendata 100
  3. hadoop jar /usr/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.5-alpha.jar teravalidate gendata reportdata

Approach

We are taking an iterative, depth-first approach to packaging. We do not have all the dependencies mapped out ahead of time. Dependencies are being tabulated into two groups:

missing - the dependency being requested from a hadoop-common pom has not yet been packaged, reviewed or generated into fedora repos
broken - the dependency requested is out of date with current fedora versions, and patches must be developed for inclusion in a hadoop rpm build that address any build, API or source code deltas

Note that a dependency may show up in both of these tables.

Anyone who wants to help should find an available dependency below, edit the table changing the state to Active and packager to yourself.

If you are lucky enough to pick a dependency that itself has unpackaged dependencies, identify the sub-dependencies and add them to the bottom of the Dependencies table below, change your current dependency to Blocked and repeat.

If your dependency is already packaged but the version is incompatible, contact the package owner and resolve the incompatibility in a mutually satisfactory way. For instance:

If the version available in Fedora is older, explore updating the package. If that is not possible, explore creating a package that includes a version in its name, e.g. pkgnameXY. Ultimately, the most recent version in Fedora should have the name pkgname while older versions have pkgnameXY. It may take a full Fedora release to rationalize package names. Make a note in the Dependencies table.

If the version you need is older than the packaged version, consider creating a patch to use the newer version. If a patch is not viable, proceed by packaging the dependency with a version in its name, e.g. pkgnameXY. Make a note in the Dependencies table.

There is tattletale dependency graph data for both the baseline branch and the fedora development branch.

Running and debugging the unit test suite is discussed in the test suite section below and results are maintained in the test suite results table.

You will run into situations where the Apache Hadoop source needs to be patched to handle the Fedora version of a dependency. Those patches are candidates to propose upstream, are tracked in the upstream patch tracking table, and maintained in the source repositories below. Any changes that are required to conform to Fedora's packaging guidelines or deal with a package naming issue should be contained to the hadoop spec file.

In handling patches, the intention of this process is to isolate changes to a single dependency so patches can be created that can be consumed upstream. It is important that changes to the source be isolated to 1 dependency and the changes must be self-contained. A dependency is not necessarily a single jar file. Changes to a dependency should entail everything needed to use the jar files from a later release of the dependency.

Source repositories:

https://github.com/fedora-bigdata/hadoop-common Fork of Apache Hadoop for changes required to support compilation on Fedora
https://github.com/fedora-bigdata/hadoop-rpm Spec and supporting files for generating an RPM for Fedora

Dependency Branches

All code/build changes to Apache Hadoop should be performed on a branch in the hadoop-common repo that should be based off the

branch-2.0.5-alpha

branch and should following this naming convention:

fedora-patch-<dependency>

Where <dependency> is the name of the dependency being worked on. Changes to this branch should ONLY relate to the dependency being worked on. Do not include the dependency version in the branch name. These branches will be updated as needed because of Fedora or Hadoop updates until they are accepted upstream by Apache Hadoop. Not having the dependency version allows the branch to move from version 1->2->3 without confusion if it is required before accepted upstream.

Integration Branch

An integration branch should be created in the hadoop-common repository that corresponds with the release version being packaged using the following naming convention:

fedora-<version>-integration

where <ver> is the hadoop version being packaged. All branches containing changes that have not yet been accepted upstream should be merged to the integration branch and the result should pass the build and all tests. Once this is complete a patch should be generated and pushed to the hadoop-rpm repository.

Test suite

In order to attempt to run any part of the test suite, you must first build the components (F19):

git clone git://github.com/fedora-bigdata/hadoop-common.git
cd hadoop-common
git checkout -b  fedora19-2.0.5-alpha-test origin/fedora19-2.0.5-alpha-test
mvn-rpmbuild -Pdist,native -DskipTest -DskipTests -DskipIT install

If you are interested in the whole ball of wax then

mvn-rpmbuild -X -Dorg.apache.jasper.compiler.disablejsr199=true^[1] test

and go mow a football field or knit a sweater. Note that this could still result in spurious failures. Add -Dmaven.test.failure.ignore=true to the above line if you're seeking just test errors.

The fedora19-2.0.5-alpha-test branch excludes identified consistently failing tests. You can edit your copy of hadoop-project/pom.xml to bring any of them back into play.

If you are interested in investigating specific failures such as active ones from the table above then target the module, test class, and even method as you see fit:

mvn-rpmbuild -X -pl :hadoop-common test -Dtest=TestSSLHttpServer#testEcho

All your hard work results in a patch? Great! Hit a contributor up with it and we'll review and apply if everything looks cool.

This option is required to ensure the test of TestHttpServer#testContentTypes passes due to the use of glassfish JSP support.

Packager tips

mvn-rpmbuild utility will ONLY resolve from system repo
mvn-local will resolve from system repo first then fallback to maven if unresolved
- can be used to find the delta between system repo packages available and missing dependencies that can be viewed in the .m2 local maven repo (find ~/.m2/repository -name '*.jar')
-Dmaven.local.debug=true
- reveals how JPP lookups are executed per dependency: useful for finding groupId,artifactId mismatches
-Dmaven.test.skip=true
- tells maven to skip test runs AND compilation
- useful for unblocking end-to-end build

An alternative to gmaven:

apply a patch with the following content where required
test support is not guaranteed, should not work.
