Readme for IBM® Spectrum Conductor 2.4.1 Interim Fix 543319

Readme file for: IBM Spectrum Conductor
Product/Component Release: 2.4.1
Update Name: Interim Fix 543319
Fix ID: sc-2.4.1-build543319
Publication date: May 21, 2020

Interim fix contains an updated Jupyter 5.4.0 notebook package with several enhancements for Jupyter with IBM Spectrum Conductor 2.4.1:

·  Support for Jupyter Enterprise Gateway 2.1.1. Requires notebook package version 6.0.0 or later.

·  Support only EGO authentication (not token authentication).

·  Jupyter notebook now sets the following headers: X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection.

·  Support for passing environment variables to the Python kernel from the notebook for CUDA_VISIBLE_DEVICES and EGO_SERVICE_CREDENTIAL by default. These values are changeable by setting JUPYTER_ENV_WHITELIST to be a list of environment variables that are available to the Python kernel. Surround each environment variable in the list with single quotation marks, and separate each with a comma, so that the list is in this format: 'ENV','ENV'. These values do not get passed to the Spark kernels as they pick up the environment variables through Spark settings.

·  The PATH of the notebook now includes the conda environment bin path.

·  A new environment variable, JEG_STARTUP_TIMEOUT, which controls timeout of Jupyter Enterprise Gateway when your machine is slow to start up. The default setting is a timeout value of 5 seconds.

2.            Installation and configuration

Follow the instructions in this section to download and install this interim fix to your cluster.

System requirements

Linux x86_64 or Linux ppc64le

Before installation

If you are updating an existing notebook, back up the notebook base data directory:

Note: For updated notebook packages, the notebook is undeployed and the new version is deployed. Therefore, if you specified the notebook base data directory under, or the same, as the notebook's deployment directory, the base data directory is removed. To retain your data, manually back up the contents of the base data directory before you update the instance group.

a.     Log in to the cluster management console as the cluster administrator.

b.     Click Workload > Instance Groups, then click the instance group that you want to check.

c.     Click Manage, and then Configure.

d.     In the Basic Settings tab, click the Configuration link in the Notebooks section, then check the Base data directory value.

Note: If the notebook base data directory is under or is the same as the notebook’s deployment directory, back up the base data directory by running the following commands from the command line:

mkdir -p /tmp/backup

> cp -a base_data_directory/ig_name /tmp/backup


Ensure that you
back up the notebook base data directory for each instance group that you want to upgrade.

Installation

a.        Log in to the cluster management console as the cluster administrator.

b.        Download the sc-2.4.1.0_build543319.tgz package and extract its contents to get the Jupyter-5.4.0.tar.gz file for the Jupyter 5.4.0 notebook.

c.        Add the Jupyter 5.4.0 package to your cluster:

To update an existing notebook:

1)       Click Resources > Frameworks > Notebook Management, select Jupyter, and click Configure.

2)       In the Deployment Settings tab, click Choose File in the Package section.

3)       Select the Jupyter 5.4.0 package.

4)       Click Update Notebook.

To add a new notebook:

1)     Click Resources > Frameworks > Notebook Management, and click Add.

2)     In the Deployment Settings tab, click Choose File in the Package section.

3)     Select the Jupyter 5.4.0 package.

·       Start command./scripts/start_jupyter.sh

·       Stop command./scripts/stop_jupyter.sh

·       Job monitor command./scripts/jobMonitor.sh

·       Longest update interval for job monitor: 280

5)     Check these options: Enable collaboration for the notebook, Supports SSL, Supports user impersonation, and Anaconda required

6)     Click Add.

Post installation

a.        From the cluster management console, click Workload > Instance Groups.

1)     Create a new instance group that uses Jupyter 5.4.0. For details, see Creating instance groups.

2)     If required, update your existing instance groups that use Jupyter 5.4.0. For details, see Modifying instance groups.

b.        For the backed-up instance groups, restore the notebook base data directory files:

> cp -a /tmp/backup/ig_name base_data_dircectory

c.        Verify that permissions and ownership of the replaced files are the same as they were before applying the fix. Update any file permissions or ownership as required.
