In Informatica versions till 10.2.0, settings that are to be used while running the mappings in Hadoop environments, could be configured through 'hadoopEnv.properties' file at '$INFA_HOME/services/shared/hadoop/<distribution>/infaConf' location in the Informatica server machine.
Hadoop pushdown jobs settings that can be configured to include the following, but not limited to:
Settings that are configured in 'hadoopEnv.properties' file would be applicable for all the Hadoop pushdown jobs, unless overridden at connection or mapping level.
Starting from Informatica 10.2.1 version, 'hadoopEnv.properties' file would not be available in Informatica server machine. For ease of use, the configuration of all the Hadoop pushdown job settings has been moved to the 'Hadoop Pushdown connection'. As a result, all the settings can be configured directly, either from Informatica Developer client or from Informatica Administrator console.
For more information on the updated 'Hadoop connection' properties, refer to the following documentation:
