Gluent Node Upgrade¶
Table of Contents
Introduction¶
This document includes the upgrade steps for the Gluent Node.
Upgrade Software Installation¶
Perform the following actions as the owner of the existing Gluent Data Platform installation.
Backup Existing Software¶
Source the Gluent Data Platform environment file and run backup commands:
$ . <OFFLOAD_HOME>/conf/offload.env
$ cd $OFFLOAD_HOME/..
$ for f in offload/conf/{offload.env,datad.conf,datad.properties,*.xml,*.key}; do [ ! -f $f ] || cp $f .; done
$ mv offload offload.$(date +%Y.%m.%d_%H.%M.%S)
Unpack New Software¶
Unpack the install tarball (gluent_offload_<version>.tar.bz2):
Note
When unpacking, an offload directory will be created if it does not exist. The offload directory is referred to as <OFFLOAD_HOME> and an environment variable ($OFFLOAD_HOME) will be set when offload.env is sourced.
$ cd <Gluent Data Platform Base Directory>
$ tar xpf <Gluent Data Platform Installation Media Directory>/gluent_offload_<version>.tar.bz2
Restore Configuration Files¶
Copy configuration files into new $OFFLOAD_HOME:
$ for f in {offload.env,datad.conf,datad.properties,*.xml,*.key}; do [ ! -f $f ] || cp $f offload/conf; done
Upgrade Spark Standalone¶
All commands should be run as the Gluent Data Platform OS User.
Backup Configuration File¶

$ cd /opt/gluent
$ cp $SPARK_HOME/conf/spark-defaults.conf .
Stop Spark Standalone¶
To stop Spark Standalone issue the following commands:
$ $SPARK_HOME/sbin/stop-all.sh

Unpack New Software¶
Run the following:
$ cd /opt/gluent/
$ rm -fr transport
$ tar xf <Gluent Data Platform Installation Media Directory>/gluent_transport_spark_<version>.tar.bz2
Update Configuration File¶
