    Hive integration

    jie tao Novice


      I want to create source model for Hadoop Hive with Teiid designer on Eclipse Luna (new installed). I followed Connect to a Hadoop Source using Hive2, but in the create data source dialog I did not find hive12.

          It should appear if the driver has been successfully added to the server.  Did you modify the standalone.xml directly and perform a restart of the server?  Or did you add via CLI?

            Thx for the rapid answer. I modified standalone-teiid.xml and restarted the server.

              now I got it. I checked the .xml file and found that the modification disappeared. Do not know why this happened. Thanks again!

                but I got this error: Data source type hive12 does not exist on server JBoss AS 7.1. I do not have a Hadoop source installed. Is this a reason?

                  Can you elaborate on the error?


                  To just see the driver in Designer you do not need to have hadoop installed - just the driver needs to be installed and in the configuration.

                    I got the problem. The driver was unpacked at the "dv" directory rather than "base". I copied it to the ...base/org/apache....  But I need a driver for hive 13.1. Where can I download this?


                    Thanks again.

                      A community user pulled together the 0.13.1 jdbc driver jars in a maven pom - vchintal/hive-jdbc-jars-archive · GitHub

                        thx. I got the driver jars and created a source model with importing metadata using JDBC. I can connect to our Hive (merging completed, completed difference analasis) but then I got this error:

                        Shall I create the Hive source model in other ways?

                          That is an issue with the hive driver that is not accounted for in the Designer import logic.  Teiid does account for that, so you should be able to use the Teiid connection importer to successfully import.

                            sorry to trouble u again because I was not successful.


                            I replaced all jars of modules/system/layers/base/org/apache/hadoop/hive12/main with the jars for hive 0.13.1 and adapted the names in modue.xml. I then followed the procedure based on the link in my first message to use Teiid connection. I got error by the last step: Get DDL for the import: error deploying importVDB. My server says that metadata is invald:

                            In hive12 driver I see a hive-metastore- but no such jar exist in 0.13.1. What I have are:


                            commons-logging-1.1.3.jar         httpcore-4.2.5.jar
                            hadoop-common-2.4.0.jar           libfb303-0.9.0.jar

                            hive-service-0.13.1.jar           slf4j-api-1.7.5.jar



                            Something missing?

                              In my local testing I needed to include hive-metastore-0.13.1.jar.  I'm not sure why that's excluded from Vijay's jar set.

                                I downloaded this from maven repository, but the error is still there (is this a correct one?). Can you show me your modue.xml so that I can check if I included all jars? Thx

                                  I didn't have a pom from my earlier testing.  The jar set I was using included:













                                  Try with that set and provide the error message you are getting if it doesn't work.
