CDH2: Testing Release now with Pig, Hive, and HBase

Categories: General Hadoop HBase HDFS Hive MapReduce Pig Testing

At the beginning of September, we announced the first release of CDH2, our current testing repository. Packages in our testing repository are recommended for people who want more features and are willing to upgrade as bugs are worked out. Our testing packages pass unit and functional tests but will not have the same “soak time” as our stable packages. A testing release represents a work in progress that will eventually be promoted to stable.

We plan on pushing new packages into the testing repository every 3 to 6 weeks.  And it just so happens it is just about 3 weeks after we announced the first testing release. So it must be time for a new one. Here are some of the highlights:

  • Hadoop 0.20.1 – Bumps the hadoop package up to the 0.20.1 release and adds 133 patches worth of extra goodness
  • Alternatives for Hadoop – Now you can have both 0.18 and 0.20 installed and use the alternatives system to pick a default
  • Pig 0.50 pre-release – We included some magic to get things working out of the box with both 0.18 and 0.20
  • Hive 0.40 pre-release – Integrated with the alternatives setup out the box works with 0.18 and 0.20
  • HBase 0.20 – We worked with the HBase team to bring rpms to a yum repo near you

A project as large as Hadoop is a communal effort. Cloudera is proud to be part of that community and hope that our products and services make Hadoop even more accessible to a wider audience. We’d like to thank everyone who contributes to Hadoop, especially the Yahoo! team for all of their hard work on getting 0.20.1 released, the developers at Facebook and those working on Pig, Hive and HBase.

We are just getting the ball rolling here. You can subscribe to our CDH mailing list ( to get information about new releases as we push them out. Check out the new release, and remember to let us know what you think!

    Great news!, exactly what I was looking for.

    I have installed Hadoop 0.20 using CDH2 last week; and this is the command I used to install it using yum.

    yum install hadoop-0.20

    It installed both HDFS and MapRed; Now a couple of questons: W

    What commands should I execute to get the Hive insalled?
    Do I install this on all nodes on the cluster? or Just a new machine for the cluser?

    Any one?

    I’m also curious why Hbase deb packages aren’t available yet- is there an issue with configuration?

    We do not officially support HBase. We worked closely with the HBase team and they packaged HBase and we host those packages. The HBase guys are working on debs and when they are finished we will host those as well.
