Setting up Pentaho Data Integration 5.4.1 with Hadoop Cluster (Clouder Manager) Setting up pentaho server has the below steps. Will be referring to Pentaho Data Integration as PDI from now on. Install PDI. Make ETL (PDI) as the Gateway for HDFS, HIVE, YARN, HBASE from Cloudera Manager. Test Access to Hadoop from PDI Server. Updating configuration in PDI for Hadoop Setup. Test PDI with Hadoop. Installing Pentaho Server 5.4.1 Community Edition. Installation is very straight forward, we get a pdi.zip which needs to be extracted in the location required. Here we will be extracting the file into /opt directory on our RHEL ETL PDI Server. Extract and move the directory to /opt [root@pentaho-server ~]# unzip pdi.zip [root@pentaho-server ~]# mv data-integration /opt Create a soft Link /opt directory, we have used kettle / pentaho as the softlink. [root@pentaho-server ~]# cd opt [root@pentaho-server opt]# ln -s data-integration pentaho [root@pentaho-server opt...
