Merging with R 3.6 #355

Closed pmags closed 5 years ago

pmags commented 5 years ago

As a test i ran your caret example (code and cluster). While merging it returns the following error on stderr.txt:

running '/usr/lib/R/bin/R --slave --no-restore --no-save --no-environ --no-restore --no-site-file --file=/mnt/batch/tasks/workitems/job20190613075533/job-1/jobpreparation/wd/merger.R --args 10 10 stop'

Error in readRDS(paste0(batchJobPreparationDirectory, "/", batchJobId, : cannot read workspace version 3 written by R 3.6.0; need R 3.5.0 or newer Execution halted

Downgrading to R 3.5.3 on my machine solved the problem and it merged without a problem. Bypassing the merge step and compiling locally does solve the problem too. But given that we would like to use the latest R version on our machine (using different R versions is easy on windows but not so friendly on mac on linux) is it possible for you to look into this issue ?

If you run these commands and restart your session, devtools::install_github("Azure/rAzureBatch", ref="fix/v3.7-support") devtools::install_github("Azure/doAzureParallel", ref="fix/v3.7-support")

Thanks, Brian

I've updated doAzureParallel with the 3.6 support. 

devtools::install_github("Azure/doAzureParallel", ref = "v0.8.0")
