Step 3. Update hadoopEnv.properties

Step 3. Update hadoopEnv.properties

Update the
hadoopEnv.properties
file on each node where the Data Integration Service runs to configure an additional Blaze instance.
Open
hadoopEnv.properties
and back it up before you configure it. You can find the
hadoopEnv.properties
file in the following location:
<Informatica installation directory>/services/shared/hadoop/<distribution name>_<version number>/infaConf

Optionally Create a New Namespace

When the machine where the Data Integration Service runs contains two domains running on the same version of Informatica, you configure a new Blaze instance on the domain where you want to run the new Blaze instance.
In the "Advanced Configuration" section of
hadoopEnv.properties
, type the following property to designate a namespace for the Data Integration Service.
infagrid.cadi.namespace
Namespace for the Data Integration Service to use.
Configure the property as follows:
infagrid.cadi.namespace=<unique value>
For example,
infagrid.cadi.namespace=TestUser1_namespace

Configure Ports

Search for the following properties and enter port numbers that no other cluster processes use.
infagrid.blaze.console.jsfport
JSF port for the Blaze engine console.
Configure the property as follows:
infagrid.blaze.console.jsfport=<unique value>
For example,
infagrid.blaze.console.jsfport=9090
infagrid.blaze.console.httpport
HTTP port for the Blaze engine console.
Configure the property as follows:
infagrid.blaze.console.httpport=<unique value>
For example,
infagrid.blaze.console.httpport=9091

Configure Directory Paths

Search for the following properties and enter paths for the Blaze service logs and persistent logs.
infagrid.node.local.root.log.dir
Path for the Blaze service logs.
This is the path that you configured in Step 1 as the local services log directory.
Configure the property as follows:
infagrid.node.local.root.log.dir=<directory path>
For example,
infagrid.node.local.root.log.dir=/opt/Informatica/blazeLogs
infacal.hadoop.logs.directory
Path in HDFS for the persistent Blaze logs.
This is the path that you configured in Step 1 as the persistent log directory.
Configure the property as follows:
infacal.hadoop.logs.directory=<directory path>
For example,
infacal.hadoop.logs.directory=infacal.hadoop.logs.directory=/var/log/Hadoop-yarn/apps/Informatica
