RHive not working in AE5

Please list the packages you have installed. I assume you've installed a Java JVM too? We don't add that as a dependency for rJava because we want people to be able to use their existing Java infrastructure.

No JVM. I used the Hadoop-Spark template in AE5 and only added the r-rhive package manually.

OK, can you do a conda list please? You need to install your own JDK. If I'd made it a strict dependency then companies would not be able to use their own Java software and we felt that was sub-optimal.

You should be able to conda install openjdk though.

BTW this repo is redundant now. No packages are developed here. The recipe for r-rhive is: https://github.com/AnacondaRecipes/aggregateR/tree/master/r-rhive-feedstock

I added openjdk and the error changed slightly. Now "java -version" does work at the Terminal. Output of "conda list" attached.

OK, I'm not sure why you have R 3.4.2 here since 3.4.3 has been out for at least a month, but regardless, as I said you need to install Java somehow. conda install openjdk is one way.

Configuring Java did the trick.

I have R 3.4.2 because that's what's in the AE5 Hadoop-Spark project template.

I cannot reproduce this. From an official docker centos6 image (centos:6) I tried the following:

/opt/conda/bin/conda create -y -n r342_rhive_openjdk r-base=3.4.2 r-rhive openjdk -c r -c https://repo.continuum.io/pkgs/main
. /opt/conda/bin/activate r342_rhive_openjdk
Rscript -e 'library(RHive)'

.. and received the following output:

Loading required package: rJava
Loading required package: methods
Loading required package: Rserve

Configuring Java did the trick.

You should not need to do this, calling conda activate on any environment that contains r-base will run R CMD javareconf at this time.

Does AE5 not activate environments?
