Developer Tool Configuration
Effective in version 10.2.1, you can create a Metadata Access Service. The Metadata Access Service is an application service that allows the Developer tool to access Hadoop connection information to import and preview metadata. When you import an object from a Hadoop cluster, the following adapters use Metadata Access Service to extract the object metadata at design time:
- PowerExchange for HBase
- PowerExchange for HDFS
- PowerExchange for Hive
- PowerExchange for MapR-DB
Previously, you performed the following steps manually on each Developer tool to establish communication between the Developer tool machine and Hadoop cluster at design time:
- Extracted cluster configuration files.
krb5.ini file to import metadata from Hive, HBase, and complex file sources from a kerberos-enabled Hadoop cluster.
The Metadata Access Service eliminates the need to configure each Developer tool machine for design-time connectivity to Hadoop cluster.
