Hi community,
I have created a RLang Procedure (using RServe) to implement ARIMA models for some forecasting.
The procedure is then called via SQLScript, which provides it with the necessary input data.
Now I would like to display the results via UI5 and therefore created a XSJS file that uses a CallableStatement.
Unfortunately an column store error exception is thrown, when I visit the URL of the XSJS file in my browser.
The JavaScript and SQLScript/R syntax should be correct, because I can call the procedure (including R-Call) successfully in HANA Studio as well as via a JAVA program using JDBC.
Furthermore, when the R-Call is excluded, also the XSJS variant works correctly.
I located the following error message within the HANA logs:
[114942]{450017}[-3010622] 2013-04-12 22:12:51.678725 e cePlanExec cePlanExecutor.cpp(06157) : Error during Plan execution of model BI_PROJECT_TMP:_SYS_SS_CE_978205_INS (-1), reason: BI_PROJECT_TMP.R_WRAPPER_TMP: line 8 col 2 (at pos 173): GenericFailure exception: column store error: search table error: [2620] BI_PROJECT_TMP.R_WRAPPER: line 13 col 2 (at pos 394): InternalFatal exception: Connection error: Unable to connect with Rserve.;None of the Rserve can be connected: 127.0.0.1:30520: Cannot connect to the host with the port;
It seems like there is a problem with the connection to RServe, but I wonder why it still works with JAVA.
Has someone experienced a simliar behavior or even knows a solution?
Thank you and best regards,
Fabian
