parameter --hive-import is supported and working correctly when you're running Sqoop from command line. It's known to not work correctly when you run Sqoop from Oozie and thus it's not supported only when running from Oozie.
The recommended workaround is to split your Sqoop action into two actions instead:
* In first Sqoop action load data into temporary directory on HDFS
* In subsequent second Hive action load data from temporary directory into Hive
