oci-hdfs-connector provides the public HDFS connector that integrates with the Oracle Cloud Infrastructure Object Storage Service.
The project is open source and maintained by Oracle Corp. The home page for the project is here.
See the documentation for details.
Examples can be found here.
Full documentation, including prerequisites and installation and configuration instructions, can be found here.
HDFS Connector provides support for delegation token configurator that injects a delegation token on every request. This can be done by setting the delegation token file path in an environment variable OCI_DELEGATION_TOKEN_FILE or by setting the Hadoop property fs.oci.delegation.token.filepath
API reference can be found here.
See the “Questions or Feedback?” section here.
The first three numbers of HDFS connector version represent the Hadoop version that the connector was compiled and tested against. The next three numbers are for the platform, major and minor versions respectively.
- Minor version is incremented when there are no breaking changes
- Major version is incremented when there are breaking changes which might affect some users
- Platform version is incremented when there are bigger important breaking changes which would affect many users
For example, in HDFS connector version 3.3.1.x.y.z, 3.3.1 is for the Hadoop version being used and x.y.z refers to the {platform}.{major}.{minor} version of the HDFS connector.
Building HDFS connector relies on Maven artifacts that are provided by the Java SDK. To obtain the artifacts, you must download the Java SDK and build it locally. You can then build the HDFS connector.
Important: The Java SDK file version that you download from the Oracle Releases page must match the HDFS connector version, which you can find in the hdfs-connector/pom.xml file in the tag block that has the groupId attribute com.oracle.oci.sdk.
See CHANGELOG.

Details: If you are using version 3.2.1.1 or earlier of the OCI HDFS Connector and you use a RefreshableOnNotAuthenticatedProvider (e.g. InstancePrincipalsCustomAuthenticator, or generally for Resource Principals or Instance Principals) you may be affected by silent data corruption.
Workaround: Update the OCI HDFS Connector to version 3.2.1.3 or later. For more information about this issue and workarounds, see Potential data corruption issue for OCI HDFS Connector with RefreshableOnNotAuthenticatedProvider.
