Developer Tool Tasks

Perform tasks on the machine that hosts the Developer tool. Update configuration files to enable communication with the Hadoop cluster and to enable high availability between the Developer tool and the cluster. Update connection properties to enable high availability between the Data Integration Service and the cluster.
Before you perform configuration tasks for the Developer tool, copy configuration files to the machine that hosts the Developer tool.
  1. 1. Find the following files on the Resource Manager node of the cluster:
  2. 2. Copy the files to the following location on the machine that hosts the Developer tool: <Informatica installation directory>/clients/DeveloperClient/Hadoop/<Hadoop distribution><version>/conf

Configure Files on the Developer Tool

Configure files on the Developer tool client machine to create, edit and run mappings on the MapR cluster.

run.bat

Edit the run.bat file to enable Developer tool launch settings for MapR.
You can find run.bat in the following directory on the machine where the Developer tool runs: <Informatica installation directory>\<version_number>\clients\DeveloperClient
Edit run.bat to include the MAPR_HOME environment variable and the -clean settings. For example, include the following lines:
<Informatica installation directory>\clients\DeveloperClient\hadoop\mapr_5.2.0
developerCore.exe -clean

developerCore.ini

Edit the developerCore.ini file to enable communication between the Developer tool and the Hadoop cluster.
You can find developerCore.ini in the following directory: <Informatica installation directory>\clients\DeveloperClient
Configure the following properties:
-Dmapr.library.flatclass -Djava.library.path
Path to the Java library on the machine that hosts the Developer tool.
Use the following value: hadoop\mapr_5.2.0\lib\native\Win64;bin;..\DT\bin
-DINFA_HADOOP_DIST_DIR
Path to the Hadoop distribution directory on the cluster. Use the following value: hadoop\<distribution>_<version>
For example, -DINFA_HADOOP_DIST_DIR=hadoop\mapr_5.2.0

hive-site.xml

Edit the hive-site.xml file. You can find hive-site.xml in the following directory: <Informatica installation directory>\clients\DeveloperClient\hadoop\mapr_<version_number>\conf\
Add the following property to hive-site.xml to enable SASL:
<property>
<name>hive.metastore.sasl.enabled</name>
<value>true</value>
</property>
