myesp failed to start after enabled "R support within HPCC"

[rameshpachamuthu]

Hi,

To explore R support within HPCC, I have followed instructions given in Installing_and_RunningTheHPCCPlatform-6.0.2-1(page no 120). I have installed both Rccp & RInside packages for R with out any issue. After this when I have restarted HPCC server, myesp component failed to start. I could find error message 'segfault at 0 ip 00000033e00ec942 sp 00007fff7c1dfbb8 error 4 in "libR.so"[33e0000000+27e000]' in esp.log file. Since libR.so is related to R, I have uninstalled the above two packages and tried to start myesp but it is failed again.

Kindly someone help me to identify what went wrong.

Note: HPCC server was up when I have installed the two packages in R. I am not sure weather this could be the cause.

Regards,
Ramesh

Hi Ramesh,

Checking with the HPCC team, you may have something wrong in your configuration changes.

From the HPCC team:
Hi –

For our PXE booted nodes, here is how we go about installing the platform with R.

1. Yum install the HPCCSystems platform RPM to resolve dependency issues.
2. Yum install R-core-devel package
3. Fetch copies of Rcpp (I’m using 0.12.1), RInside (0.2.12), and inline (0.3.14), I suspect the latest versions will work as well but I can’t say for sure.
https://cran.r-project.org/web/packages/Rcpp/index.html
https://cran.r-project.org/web/packages ... index.html
https://cran.r-project.org/web/packages ... index.html
4. R CMD INSTALL Rcpp_0.12.1.tar.gz
5. R CMD INSTALL RInside_0.2.12.tar.gz
6. R CMD INSTALL inline_0.3.14.tar.gz
7. Start up the HPCC services.

This is what you do on ALL nodes that run HPCC processes… it might be that it just needs doing on a servers running specific HPCC processes, but this gets done on everything in our world. That way it covers everything it might be needed on. Plus it then gives you flexibility if you redefine your env, you’ll already have R installed on all servers.
