LDAP Authentication for Hive in Big Data Management®

LDAP Authentication for Hive in Big Data Management®

Overview

Overview

Big Data Management supports Kerberos authentication for Hadoop clusters. Based on the Hadoop distribution, you can configure Hive to use LDAP or Kerberos authentication. When you configure Hive for authentication, the Hive metastore, HiveServer2, and the Hive clients use the authentication mechanism.
Cloudera CDH and Hortonworks HDP support LDAP authentication for HiveServer2. The Data Integration Service depends on HiveServer2 for the following tasks:
  • Run mappings in the native environment
  • Preview data
  • Access Hive metadata at run time
  • Access Hive tables enabled for SQL authorization
  • Access bucketed or ACID Hive tables
Based on whether the Hadoop cluster uses Kerberos authentication, Big Data Management has certain guidelines to use LDAP authentication for Hive. To access Hive sources and targets, you can use LDAP authentication. However, to run mappings on a cluster that uses Kerberos authentication, the Data Integration Service always uses Kerberos authentication. It does not use LDAP authentication because the mappings can contain sources and targets other than Hive. For example, a mapping can read from a Hive source and write to an HDFS target.
