You have the following
options for managing updates to the SAS High-Performance Analytics
environment:
-
Delete the SAS High-Performance
Analytics environment and install the newer version.
See the procedure later
in this topic.
-
Rename the root installation directory
for the current SAS High-Performance Analytics environment, and install
the newer version under the previous root installation directory.
-
Do nothing to the current SAS High-Performance
Analytics environment, and install the new version under a new installation
directory.
When you change the
path of the SAS High-Performance Analytics environment, you have to
also have to reconfigure the SAS LASR Analytic Server to point to
the new path. See “Add a SAS LASR Analytic Server” in
the
SAS Visual Analytics: Administration Guide.
Updating your deployment
of the SAS High-Performance Analytics environment consists of deleting
the deployment and reinstalling the newer version. To update the SAS
High-Performance Analytics environment, follow these steps:
-
If you are also updating
your co-located Hadoop deployment, update Hadoop first, then the SAS
High-Performance Analytics environment.
-
Check that there are
no analytics environment processes running on any machine:
ps –ef
| grep TKGrid
If you find any TKGrid
processes, terminate them.
Tip
You can issue a single
simsh command
to simultaneously check all the machines in the cluster:
/HPA-environment-installation-directory/bin/simsh
ps –ef | grep TKGrid.
-
Delete the analytics
environment installation directory on every machine in the cluster:
rm -r -f /HPA-environment-install-dir
Tip
You can issue a single
simsh command
to simultaneously remove the environment install directories on all
the machines in the cluster:
/HPA-environment-installation-directory/bin/simsh
rm -r -f /HPA-environment-installation-directory.
