Starting from Informatica 10.2.1 version, '' file would not be available in Informatica server machine. For ease of use, Hadoop cluster specific Environment variable settings, LD_LIBRARY_PATH settings and Hadoop Execution engine properties that are to be used during Informatica jobs, have been moved to the 'Hadoop Pushdown connection'. 

For more information on the updated 'Hadoop connection' properties, refer to the following documentation:​

 To resolve the issue, you need to configure 'NLS_LANG' environment variable set in the 'Hadoop Pushdown' connection used for running the job. 


Perform the following steps from Informatica 10.2.1 to configure the 'NLS_LANG' environment variable setting, which would have been configured through '' file in earlier versions:

  1. Log in to Informatica Administrator console or launch Informatica Developer client.
  2. Navigate to 'Connections' tab in case of Informatica Administrator console and 'Windows > Preferences > Connections > [Domain]> Cluster > Hadoop', when Developer client is used.
  3. Select the 'Hadoop Pushdown' connection, being used for running the jobs.
  4. Edit the 'Hadoop Cluster Properties' section in the connection.
  5. In the 'Hadoop Cluster Properties' window, edit the 'Cluster Environment Variables'  attribute.
  6. In the newly opened window, use 'New' button to add the Environment variable setting as follows:









To add 'NLS_LANG' environment variable with 'AMERICAN_AMERICA.AL32UTF8' as value, enter the details as follows:









   7.  Once Environment variable setting has been added, save the changes.

   8.  Stop running Blaze Engine applications and then re-run the mapping in 'Blaze' mode, so as to start 'Blaze Engine' with updated settings. For more information on starting and stopping Blaze application, refer to the following KB article:


On running new Hadoop pushdown job, the configured environment variable settings would be used and the encountered 'UTF-8 Transliteration' error would get resolved.
