Hi Alex, You have the right command for running individual tests. Most tests don't use MiniOozie or LocalOozie; they just start the Services directly (that's probably something we should be more consistent about). The MiniMRCluster is a little trickier: we start up one MiniMRCluster per maven Module and reuse it for all tests within that module (this saves on overhead of stopping/starting Hadoop for every test). Some code in XTestCase takes care of this.
That's odd that you're getting a ConnectionRefused Exception like that. It sounds like maybe the MiniMRCluster isn't starting up correctly or something. You could try changing the log level of Hadoop classes to maybe get more details on failures there? Another thing you could try is going through the test with a debugger and making sure that Hadoop is running in the test (this is easiest to do by running the test from an IDE rather than from the CLI). - Robert On Tue, Mar 24, 2015 at 4:23 PM, Alex Bain <[email protected]> wrote: > Hello, > > I'm new to Oozie and am working on implementing it at LinkedIn.
