Big Data

This section describes new Big Data features in version 9.6.1.
You can push high precision Decimal data types to a Hive environment that uses Hive 0.11 and above.
If the mapping is not enabled for high precision, the Data Integration Service converts all decimal values to double values.
If the mapping is enabled for high precision, the Data Integration Service converts decimal values with a precision greater than 28 to double values.
For more information, see the
Informatica 9.6.1 Big Data Edition User Guide
.
In the Hive connection, you specify the following properties:
  • Enter advanced Hive or Hadoop properties to configure or override Hive or Hadoop cluster properties in
    hive-site.xml
    on the machine on which the Data Integration Service runs.
  • Enter the user name of the user that the Data Integration Service impersonates to run mappings on the Hadoop cluster.
For more information, see the
Informatica 9.6.1 Big Data Edition User Guide
.
You can enable the Data Integration Service to run mapping and workflow jobs on a Hadoop cluster that uses Kerberos authentication. The Hadoop cluster authenticates the SPN of the Data Integration Service user account to run mapping and workflow jobs on the Hadoop cluster. To enable another user to run jobs on the Hadoop cluster, you can configure the SPN of the Data Integration Service user account to impersonate another user account.
For more information, see the
Informatica 9.6.1 Big Data Edition User Guide
.
You can enable mappings to run on the following Hadoop distributions:
  • Cloudera CDH 5.0
  • Hortonworks HDP 2.0
  • MapR 3.1
  • Pivotal HD 1.1
