Cannot Create Library with R language - Error ROLLBACK 2175

Hello all,

 

I have been using R with Vertica for sometime now. I have not had any issues integrating my R Functions with Vertica until recently. I always follow the same commands when creating a library - 

 

drop library libName cascade;
create library libName AS '/opt/vertica/sdk/examples/RFunctions/function1.R' LANGUAGE 'R';
create transform function libBame AS LANGUAGE 'R' NAME 'libNameFactory' LIBRARY libName;

 

And Vertica would create the function.

 

However, now when I try to create a library in Vertica - I recieve this error - 

 

create library libName AS '/opt/vertica/sdk/examples/RFunctions/function1.R' LANGUAGE 'R';

ROLLBACK 2175:  An error occurred when loading library file on node v_dbname_node0001, message:

Couldn't create new UDx side process, failed to get UDx side process info from zygote: UDx side process has exited abnormally.

 

I have never seen this error before and am not even sure where to start looking for the problem. I would really appreciate it if I could get some guidance on this error.

 

Thanks in advance!

    Hi Ryan,

     

        Could you please check if function1.R is present in exact path as mentioned below on the participating nodes. Please check PATH & LD_LIBRARY_PATH environment variables make sure that  see that those don't have more than 1 occurrences of R function.

     

    -Regards,

     Sruthi

     

     

     

  • Thank you for the response - I am not sure how to check my PATH and LD_LIBRARY_PATH

     

    UPDATE - 

     

    I am unable to do any type of queries with the library names - I just performed the query

     

    SELECT * FROM USER_LIBRARY_MANIFEST;

     

    and receieved this error - 

     

    ERROR 2929:  Couldn't create new UDx side process, failed to get UDx side process info from zygote: UDx side process has exited abnormally

     

    I looked at the log files from vertica.log and I have this error - 

     

    Couldn't create new UDx side process, failed to get UDx side process info from zygote: UDx side process has exited abnormally
    LOCATION: createNewUDxSideProcess, /scratch_a/release/vbuild/vertica/EE/EEUtil/UDxFenceSupport.cpp:511

    Hi,

     

     Could you also please check if /opt/vertica/R/library/Rcpp/lib/ on node001 has all files when compared to the other nodes??

     

    -Regards,

     Sruthi
