Hi all,

Did some one experiment Oracle NoSQL with Hadoop want to share the results?

Thanks

    This is a very broad question and therefore difficult to answer. Is there anything in particular you are asking about in terms of Hadoop and Oracle NoSQL Database?

    Oracle NoSQL Database is packaged with a Hadoop Input Stream. See the doc at:

    http://docs.oracle.com/cd/NOSQL/html/javadoc/oracle/kv/hadoop/package-summary.html

    There is also an example referenced in that javadoc.

    Did Oracle realize a business test with map/reduce?
    To see how the usage of map/reduce with Oracle NoSQL database will improve performance on some jobs.

    Oracle NoSQL Database includes Hadoop based example \kv-1.2.123\examples\hadoop\CountMinorKeys.java.
    To test the example:
    1. Add the Hadoop related Jar files from the \hadoop-0.22.0\lib directory to classpath.
    2. Configure a Hadoop Cluster
    3. Start the Hadoop Cluster
    4. Run a Map/Reduce Job

    I'm wondering if the original question was trying to understand whether Map Reduce runs on NoSQL DB. E.g. NoSQL is a different storage under MapReduce. To ensure no confusion remains: you do not run Map Reduce on the NoSQL DB storage infrastucture. You use an input format and get data out of NoSQL and process on Hadoop...

    Map/Reduce runs on Hadoop with Oracle NoSQL database data.

    Thanks Charles

    Is there anything you suggest at this point to get around this issue?

    Based on the information found on the link below, the issue seems to have been fixed on Map/Reduce 0.21.0

    https://issues.apache.org/jira/browse/MAPREDUCE-954

    I can either wait till Cludera release next CDH version (hopefully will include the fix) or try to apply the patch that is attached to MAPREDUCE-954 bug however It is not 100% clear to me how to apply it

    Any detailed instructions how to apply this patch would be much appreciated.

    According to the link below, the bug fix has been included in Map/Reduce 0.21.0. Unfortunately the lastest CHD 4.1.2 includes Map/Reduce 0.20.0.

    https://issues.apache.org/jira/browse/MAPREDUCE-954

    I can either wait for the next CDH version (hopefully will include the fix) or try to apply the patch that is attached to MAPREDUCE-954 link above.

    However it is not entire clear to me how to apply the patch.

    Any detailed instruction how to apply to make the "CountMinorKeys" sample work, would be appreciated.

    Cheers
