Does it work with hadoop 2.0.0?

[gadodia]

Hey its not an issue, just wanted to know if you guys are working on to make it run on hadoop 2.0.0.
Or is there a minor change that can make it run with hadoop 2.0.0 ?

At the moment it's not supported. I was anticipating adding it very soon.

We forked the project and this one works for hadoop 2.0 and later also.

Very nice. If you'd like to PR this back into hadoop-sstable let me know.

Sure. We will do that.

I want to add comments about the supporting of Hadoop 2. I have no problem to use the version 0.1.2 on Hadoop version 2.2, but I do have a problem to use the release 0.1.2 jar file from Maven repository.

1. It looks like the ONLY jar file of version 0.1.2 includes the hadoop 1.0.4 binary with it, which causes problem to use it on a hadoop 2.x environment. For example, I create the following section in my pom.xml file:

    <dependency>
        <groupId>com.fullcontact</groupId>
        <artifactId>hadoop-sstable</artifactId>
        <version>0.1.2</version>
        <scope>compile</scope>
        <exclusions>
            <exclusion>
                <groupId>org.apache.cassandra</groupId>
                <artifactId>cassandra-all</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.apache.hadoop</groupId>
                <artifactId>hadoop-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

It will still include the hadoop 1.x binary in the final jar file, which I believe coming from "hadoop-sstable". Currently I HAVE to manually remove the "hadoop" related binary class from the jar file generated in the end. In our project, we also use "cassandra 1.2.x", which has different minor version as your guys (it won't cause any problem so far), but we are using Hadoop 2.2.

Here is my suggestion:

1. In the maven repository, can you release a jar file WITHOUT any dependence? Just include "fullcontact" related classes? I believe in that case, if I use the pom's dependence as above, It will include all other dependence jar from "hadoop-sstable", but exclude "hadoop-core", which is a wrong version for our environment. I am not a maven expert, but my guess is that due to you guys only release one jar file including all the dependences, maven has no way to exclude "hadoop" in my project.

Other than that, so far I didn't see any issue to be used in hadoop 2.2.

Thanks

You can exclude hadoop when you pull in the jar, but you'll run into trouble with any linkage-related changes, e.g. interfaces that are now abstract classes.

We'll likely take the approach of releasing a few different flavors that are targeted at different profiles (e.g. Hadoop 1, Hadoop 2, possibly differentiate CDHs). We're still evaluating for sure, and @bvanberg has the final say in the end.
