I wrote a few reporting scripts in Perl that connected to Hive via the Thrift interface.
Since we upgraded CDH to 4.2.0 and hiveserver2 was installed (with Hive 0.10.0) the scripts no longer ran due to the API changes. I regenerated the Perl modules from the .thrift files and have tried to translate the Java examples I’ve found online, but cannot for the life of me get it working with the new interface. The Java examples seem to use a TOpenSessionReq class but I cannot find this anywhere in the generated Perl modules. If I try to skip that part and go straight to $client->OpenSession() without an argument, the TCLIService module itself complains that it cannot create a TOpenSessionResp object because the class is not loaded. I have attached example code. Can anyone advise me on how to get past this block? -- Best wishes, Dave Cardwell. http://davecardwell.co.uk/
