The first three numbers of HDFS connector version are Hadoop version that the connector was compiled and tested against.
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.
