2. Products or components affected
· IBM Spectrum Conductor with Spark v2.2.1
· Spark version 1.6.1, 2.1.1, 2.2.0
· Linux 64-bit
· cws-2.2.1-build487185
3. Installation and configuration
System requirements
· Linux 64-bit
Before installation
1. IBM Spectrum Conductor with Spark v2.2.1 must be installed on a supported operating system. For details, see https://www.ibm.com/support/knowledgecenter/SSZU2E_2.2.1/installing/install_upgrade.html.
2. Log on as the cluster
administrator and stop the ascd service:
>
egosh user logon -u Admin -x Admin
>
egosh service stop ascd
3. For
recovery purposes, log on to each management host in the cluster and back up
the following file to another directory:
$EGO_TOP/ascd/2.2.1/lib/asc-common-2.2.1.jar
$EGO_TOP/ascd/2.2.1/lib/asc-core-2.2.1.jar
Installation
1. Log on to
each management host in your cluster as the cluster administrator and decompress the cws-2.2.1.0_build487185.tgz package to the directory
where you installed IBM Spectrum Conductor with Spark.
>
mkdir -p /tmp/fix487185
> tar
zoxf cws-2.2.1.0_build487185.tgz -C /tmp/fix487185
>
tar zoxf /tmp/fix487185/lifecycle.tgz -C $EGO_TOP
2. Delete all
subdirectories and files in the ascd/workarea directory:
>
rm –rf $EGO_TOP/ascd/workarea/*
NOTE: If you
changed the default configuration for the WLP_OUTPUT_DIR environment
variable and APPEND_HOSTNAME_TO_WLP_OUTPUT_DIR is set to true in the $EGO_CONFDIR/wlp.conf file, you must clean up the $WLP_OUTPUT_DIR/ascd_hostname/ascd/workarea/ directory.
3. Start the ascd service:
> egosh
user logon -u Admin -x Admin
>
egosh service start ascd
4. On the client machine where you have a browser, decompress the cws-2.2.1.0_build487185.tgz package. For example, on Linux:
> mkdir -p /tmp/fix487185
> tar zoxf cws-2.2.1.0_build487185.tgz -C /tmp/fix487185
5. Launch a browser and clear the browser cache; then log in to the cluster management console as Admin.
6. Remove the Spark package if it exists. For example, for Spark 1.6.1:
a. Click Workload > Spark > Version Management.
b. Check 1.6.1.
c. Click Remove.
7. Add the new Spark package to your cluster. For example, for Spark 1.6.1:
a. Click Workload > Spark > Version Management.
b. Click Add.
c. Click Browse and select the /tmp/fix487185/Spark1.6.1-Conductor2.2.1.tgz package.
8. Click Add.
After installation
1. Create a new Spark instance group that uses the new Spark package, for example, Spark 1.6.1. For details, see https://www.ibm.com/support/knowledgecenter/SSZU2E_2.2.1/developing_instances/instance_create_about.html.
2. If required, upgrade your existing Spark instance groups to use the new Spark package, for example, Spark 1.6.1. For details, see https://www.ibm.com/support/knowledgecenter/SSZU2E_2.2.1/managing_instances/instance_update_spark_version.html.
For existing Spark instance groups, updating does not involve deleting and re-creating Spark instance groups. This patch takes effect for both newly created and updated Spark instance groups.
