Re: Problem running hive from eclipse
Hi, I don't know if this will help but I do a clean package separately and before running eclipse-files. This has always worked, but with a few quirks. -- Brock Noland Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Thursday, February 21, 2013 at 7:01 AM, amareshwari sriramdasu wrote: Hi, I'm trying to launch junit test from eclipse, it fails with ClassNotFoundException.

Re: Problem running hive from eclipse
make sure you have correct jar files included in your eclipse application launcher. Try this: Go to Run Configuration by right clicking on your project - click Run As - Select Run Configuration Select TestCliDriver JUNIT luncher-click on ClassPath tab- make sure all your jar files are there.

running Hive from Eclipse fails
Hi, When I try to run Hive by HiveCli.Launch I get this error: The archive: /hive-trunk/build/hadoopcore/hadoop-0.20.2/conf which is referenced by the classpath, does not exist. What should I do? Moreover, do I have to start hadoop manually before starting Hive? Thank you for your reply. Mahsa
Re: Running hive in eclipse

I looked over the build.xml under ./builtins directory, and noticed that
the compile and jar targets are both commented, and no jar is generated for
builtins
target name=compile depends=init, setup
echo message=Project: ${ant.project.name}/
!-- defer compilation until package phase --
/target
target name=jar depends=init
echo message=Project: ${ant.project.name}/
!-- defer compilation until package phase --

I then manually changed the build.xml for compile part as follows and
rebuilt the project:
target name=compile depends=init, setup
echo message=Project: ${ant.project.name}/
javac

Now the 'hive-buitins-0.8.0-SNAPSHOT.jar' is under the .build/buitins

problem and how I should run cli correctly in eclipse?

Running Hive from Eclipse
Hi folks, I am trying to run Hive from eclipse. I've set it up correctly and it is building the jars and stuff. However I face execeptions when I try to run hive queries like show tables etc. There has been a discussion on this in the mailing list previously but there was no solution provided. It runs perfectly from command line . I am making a few changes to the hive source and every time I need to jar it from the command line and run it .Is there some way to run it directly from eclipse? Please help, Thanks, JS
