Installing Supported Kernels (Servers)#

Gateway Provisioners includes tooling to create kernel specifications that support the following kernels:

  • IPython kernel (Python)

  • Apache Toree (Scala)

  • IRKernel (R)

Refer to the following for instructions on installing the respective kernels. For cluster-based environments, these steps should be performed on each applicable node of the cluster, unless noted otherwise.

Important!

For proper operation across the non-containerized clusters, the IPyKernel and IRkernel packages (not the kernel specification) must be installed on every node of the cluster available to Gateway Provisioners. For example, run pip install ipykernel on each applicable node.

Note: This step is not required for the Scala (Apache Toree) Kernel as that can be expressed as a dependency in the spark-submit invocation where the package is copied during launch.

Python Kernel (IPython kernel)#

The IPython kernel comes pre-installed with Anaconda, and we have tested with its default version of IPython kernel.

pip install --upgrade ipykernel

or

mamba install -c conda-forge ipykernel

Scala Kernel (Apache Toree)#

We have tested the latest version of Apache Toree with Scala 2.12 support.

pip install --upgrade apache_toree

or

mamba install -c conda-forge apache_toree

R Kernel (IRkernel)#

Perform the following steps on Gateway Provisioner’s hosting system as well as all worker nodes. Please refer to the IRKernel documentation for further details.

mamba install --yes --quiet -c r r-essentials r-irkernel r-argparse
# Create an R-script to run and install packages and update IRkernel
cat <<'EOF' > install_packages.R
install.packages(c('repr', 'IRdisplay', 'evaluate', 'git2r', 'crayon', 'pbdZMQ',
                   'devtools', 'uuid', 'digest', 'RCurl', 'curl', 'argparse'),
                   repos='http://cran.rstudio.com/')
devtools::install_github('IRkernel/IRkernel@0.8.14')
IRkernel::installspec(user = FALSE)
EOF
